+# actuarialsymbol
+
+Package `actuarialsymbol` provides commands to compose
+actuarial symbols of life contingencies and financial mathematics
+characterized by subscripts and superscripts on both sides of a
+principal symbol. The package also features commands to easily and
+consistently position precedence numbers above or below statuses
+in symbols for multiple lives contracts.
+
+Since the actuarial notation can get quite involved. the package
+defines a number of shortcut macros to ease entry of the most common
+elements. Appendix A of the package documentation lists the commands
+to typeset a large selection of symbols of life contingencies.

+% actuarial symbols of life contingencies and financial mathematics
+% characterized by subscripts and superscripts on both sides of a

+% in symbols for multiple lives contracts.
+%

+% \section{Introduction}
+% \label{sec:introduction}
+%
+% Actuaries denote various quantities of life contingencies like
+% present values of life insurances and life annuities, annual
+% premiums, or reserves using a whole array of symbols. The highly
+% descriptive, yet compact, notation was standardized as far back as
+% in 1898 \citep{Wolthuis:notation:2004}. \autoref{fig:mosaic} shows a
+% creative use of the notation by the graduating class of 1972 in
+% Actuarial Science at Université Laval.
+%
+% \begin{figure}[t]
+% \centering
+% \includegraphics[width=\linewidth]{mosaic}
+% \caption{``Actuariat'' (French for Actuarial Science) written
+% using actuarial symbols on the 1972 graduating class mosaic at
+% Université Laval}
+% \label{fig:mosaic}
+% \end{figure}
+%
+% \citet[Appendix~4]{Bowers:2e:1997} offer an excellent overview of
+% the composition rules for symbols of actuarial functions. In a
+% nutshell, a principal symbol, say $S$, is combined with auxiliary
+% symbols positioned in subscript or in superscript, to the left or to
+% the right. Schematically, we thus have:
+% \begin{equation}
+% \label{schema1}
+% \actsymb[\fbox{\scriptsize I}\!\;][\fbox{\scriptsize II}\!\;]%
+% {\framebox[5ex]{$S$}}{\,\fbox{\scriptsize III}}%
+% [\,\fbox{\scriptsize IV}]
+% \end{equation}
+%
+% The principal symbol is in general a single letter. The letter may
+% be ``accented'' with a bar ($\bar{A}$), double dots ($\ddot{a}$) or
+% a circle ($\mathring{e}$). When the principal symbol consists of two
+% letters, they are grouped between parentheses, as in $\IA$ or
+% $\DA*$. Most commonly, there are alphanumeric statuses in the
+% lower-right position \fbox{\small III}. Numerals can be placed above
+% or below the individual statuses to show the order of failure; we
+% will refer to these numerals as \emph{precedence numbers}. Otherwise,
+% auxiliary symbols appear lower-left \fbox{\small I}, upper-left
+% \fbox{\small II} and upper-right \fbox{\small IV}, in that order of
+% frequency.
+%
+% Principle symbols for benefit premiums, reserves and amount of
+% reduced paid-up insurance, $P$, $V$ and $W$, are combined with
+% benefit symbols unless the benefit is a level unit insurance payable
+% at the end of the year of death. In such cases, we have the
+% following symbol structure (replace $P$ by $V$ or $W$ as needed):
+% \begin{equation}
+% \label{schema2}
+% \actsymb[\fbox{\scriptsize I}\!\;][\fbox{\scriptsize II}\!\;]%
+% {\framebox[5ex]{$P$}}{}[\,\fbox{\scriptsize IV}]%
+% \bigl(\actsymb{\framebox[5ex]{$S$}}{\,\fbox{\scriptsize III}}\bigr)%
+% \end{equation}
+%
+% Perhaps the most commonly used auxiliary symbol not readily
+% available in {\LaTeX} is the ``angle'' denoting a duration $n$, as
+% in $\angln$. Package \pkg{actuarialangle} \citep{actuarialangle}
+% provides commands to create this symbol, as well as an overhead
+% angle bracket\footnote{Starting with version 2.0 dated 2017/04/10.}
+% (or ``roof'') used to emphasize joint status when ambiguity is
+% possible: $\group{xy}$. This package is imported at load time by
+% \pkg{actuarialsymbol}.
+%
+% Package \pkg{actuarialsymbol} provides a generic command to position
+% all subscripts and superscripts easily and consistently around a
+% principal symbol, a command to create two-letter symbols and two
+% commands to position precedence numbers above and below statuses.
+% Since entering actuarial symbols can get quite involved, the package
+% also defines a number of shortcuts to create the most common
+% actuarial functions of financial mathematics and life contingencies.
+%
+% \section{For the impatient}
+% \label{sec:actuarialsymbol:quickstart}
+%
+% The hurried reader may jump to \autoref{sec:shortcuts} for the
+% shortcut macros defined by the package, and to
+% \autoref{sec:comprehensive} for a comprehensive list of symbols of
+% life contingencies along with the {\LaTeX} code to compose them with
+% \pkg{actuarialsymbol} loaded. That said, in our highly biased view,
+% it remains worth reading along the fine documentation below.
+%
+% \section{Package features}
+% \label{sec:features}
+%
+% This section describes the generic commands provided by the package
+% to compose actuarial symbols. On a daily basis, one should use the
+% shortcuts of \autoref{sec:shortcuts} to ease entry of symbols.
+%
+% \subsection{Actuarial symbol}
+% \label{sec:features:actsymb}
+%
+% \begin{DescribeMacro}{\actsymb}
+% The generic command \cmd{\actsymb} typesets a principal symbol with
+% surrounding subscripts and superscripts. Its syntax is somewhat
+% unusual for {\LaTeX}, but it serves well the natural order of the
+% building blocks of a symbol and their relative prevalence:
+% \begin{quote}
+% \cmd{\actsymb}\oarg{ll}\oarg{ul}\marg{symbol}\marg{lr}\oarg{ur}
+% \end{quote}
+% Above, \meta{ll} identifies the auxiliary symbol in the lower left
+% subscript position \fbox{\small I} (following the notation in the
+% schematic representation \eqref{schema1}); \meta{ul} is the upper
+% left superscript \fbox{\small II}; \meta{symbol} is the principal
+% symbol $S$; \meta{lr} is the lower right subscript \fbox{\small
+% III}; \meta{ur} is the upper right superscript $\fbox{\small IV}$.
+% The principal symbol and the right subscript are required, the
+% other arguments are optional.
+% \begin{demo}
+% \begin{texample}
+% |\actsymb{A}{x}|
+% \producing
+% $\actsymb{A}{x}$
+% \end{texample}
+% \begin{texample}
+% |\actsymb[n]{A}{x}|
+% \producing
+% $\actsymb[n]{A}{x}$
+% \end{texample}
+% \begin{texample}
+% |\actsymb[n][2]{A}{x}|
+% \producing
+% $\actsymb[n][2]{A}{x}$
+% \end{texample}
+% \begin{texample}
+% |\actsymb[n][2]{A}{x}[(m)]|
+% \producing
+% $\actsymb[n][2]{A}{x}[(m)]$
+% \end{texample}
+% \end{demo}
+%
+% The command actually admits one more optional argument to compose
+% symbols for premiums, reserves and paid-up insurance. The extended
+% command
+% \begin{quote}
+% \cmd{\actsymb}\oarg{ll}\oarg{ul}\oarg{principle}\marg{symbol}\marg{lr}\oarg{ur}
+% \end{quote}
+% puts symbol \meta{principle} outside the parentheses in the
+% schematic representation \eqref{schema2}.
+% \begin{demo}
+% \begin{texample}[0.7]
+% |\actsymb[][][P]{\bar{A}}{x:\angln}|
+% \producing
+% $\actsymb[][][P]{\bar{A}}{x:\angln}$
+% \end{texample}
+% \begin{texample}[0.7]
+% |\actsymb[k][][V]{\bar{A}}{x}[\{1\}]|
+% \producing
+% $\actsymb[k][][V]{\bar{A}}{x}[\{1\}]$
+% \end{texample}
+% \begin{texample}[0.7]
+% |\actsymb[k][][\bar{W}]{\bar{A}}{x}|
+% \producing
+% $\actsymb[k][][\bar{W}]{\bar{A}}{x}$
+% \end{texample}
+% \end{demo}
+% \end{DescribeMacro}
+%
+% \begin{rem}
+% {\TeX} adjusts the position of a subscript downward when a
+% superscript is present:
+% \begin{displaymath}
+% A_x \quad A_x^2.
+% \end{displaymath}
+% The package maintains this behaviour. Therefore, entering the
+% symbols above using the standard operators |^| and |_| or with
+% \cmd{\actsymb} yields the same result.
+% \begin{demo}
+% \begin{texample}[0.7]
+% |A_x \quad A_x^2|
+% \producing
+% $A_x \quad A_x^2$
+% \end{texample}
+% \begin{texample}[0.7]
+% |\actsymb{A}{x} \quad \actsymb{A}{x}[2]|
+% \producing
+% $\actsymb{A}{x} \quad \actsymb{A}{x}[2]$
+% \end{texample}
+% \end{demo}
+% Furthermore, the package also ensures that the left and right
+% subscripts, when both present, are at the same level, something
+% popular ad~hoc constructions do not provide.
+% \begin{demo}
+% \begin{texample}[0.7]
+% |{}_tA_x \quad {}_tA_x^2|
+% \producing
+% ${}_tA_x \quad {}_tA_x^2$
+% \end{texample}
+% \begin{texample}[0.7]
+% |\actsymb[t]{A}{x} \quad \actsymb[t]{A}{x}[2]|
+% \producing
+% $\actsymb[t]{A}{x} \quad \actsymb[t]{A}{x}[2]$
+% \end{texample}
+% \end{demo}
+% In symbols for premiums, reserves and paid-up insurance,
+% subscripts and superscripts are aligned only around the principle
+% symbol. Authors who would prefer a uniform subscript position
+% \emph{throughout their document} should load package
+% \pkg{subdepth} \citep{subdepth}.
+% \end{rem}
+%
+% \subsection{Two-letter principal symbols}
+% \label{sec:features:twoletsymb}
+%
+% \begin{DescribeMacro}{\twoletsymb}
+% Entering two-letter principal symbols like $\DA$ as |$(DA)$| results in
+% letters that are too distant from one another: $(DA)$. To unify
+% presentation, the package provides the command
+% \begin{quote}
+% \cmd{\twoletsymb}\oarg{length}\marg{symbol\_1}\marg{symbol\_2}
+% \end{quote}
+% to group \meta{symbol\_1} and \meta{symbol\_2} between parentheses
+% with kerning\footnote{Spacing adjustment between the characters}
+% reduced by length \cmd{\twoletkern} (see below). One can also
+% reduce spacing by \meta{length} for a specific symbol.
+% \begin{demo}
+% \begin{texample}
+% |\twoletsymb{\bar{D}}{\bar{A}}|
+% \producing
+% $\twoletsymb{\bar{D}}{\bar{A}}$
+% \end{texample}
+% \begin{texample}
+% |\twoletsymb{I}{\ddot{a}}|
+% \producing
+% $\twoletsymb{I}{\ddot{a}}$
+% \end{texample}
+% \begin{texample}
+% |\twoletsymb[0.8pt]{I}{\ddot{a}}|
+% \producing
+% $\twoletsymb[0.8pt]{I}{\ddot{a}}$
+% \end{texample}
+% \end{demo}
+%
+% We expect authors to use \cmd{\twoletsymb} to define commands, not
+% directly in equations. The package already defines a number of
+% shortcuts for the main two-letter actuarial symbols; see
+% \autoref{sec:shortcuts}.
+% \end{DescribeMacro}
+%
+% \begin{DescribeMacro}{\twoletkern}
+% The standard kerning between mathematical symbols defined with
+% \cmd{\twoletsymb} is \emph{reduced} by the length
+% \cmd{\twoletkern}, by default \the\twoletkern. This value can be
+% changed as usual using \cmd{\setlength}.
+% \end{DescribeMacro}
+%
+% \subsection{Precedence numbers}
+% \label{sec:features:precedence}
+%
+% \begin{DescribeMacro}{\nthtop}
+% \begin{DescribeMacro}{\nthtop*}
+% Precedence numbers appear above or below individual statuses in
+% the right subscript \fbox{\small III} of a symbol. Commands
+% \begin{quote}
+% \cmd{\nthtop}\oarg{length}\marg{number}\marg{status} \\
+% \cmd{\nthtop*}\oarg{length}\marg{number}\marg{status}
+% \end{quote}
+% put a precedence \meta{number} above a \meta{status}, smashed so
+% that the apparent height of the status is its normal height. This is
+% normally used in the right subscript \fbox{\small III} of a symbol. With
+% \cmd{\nthtop}, the spacing between the precedence number and the
+% status is a constant \cmd{\nthtopsep} (see below). This can result
+% in precedence numbers placed at different heights if one status
+% contains an horizontal rule.
+% \begin{demo}
+% \begin{texample}[0.85]
+% |\actsymb{A}{\nthtop{1}{x}:\angln}|
+% \producing
+% \rule{0pt}{12pt}$\actsymb{A}{\nthtop{1}{x}:\angln}$
+% \end{texample}
+% \begin{texample}[0.85]
+% |\actsymb{A}{x:\nthtop{1}{\angln}}|
+% \producing
+% \rule{0pt}{12pt}$\actsymb{A}{x:\nthtop{1}{\angln}}$
+% \end{texample}
+% \begin{texample}[0.85]
+% |\actsymb{A}{\nthtop{1}{x}y:\nthtop{2}{\angln}}|
+% \producing
+% \rule{0pt}{12pt}$\actsymb{A}{\nthtop{1}{x}y:\nthtop{2}{\angln}}$
+% \end{texample}
+% \end{demo}
+% Conversely, \cmd{\nthtop*} always leaves enough space
+% \cmd{\nthtopskip} for intervening horizontal rules, resulting
+% in vertically aligned precedence numbers.
+% \begin{demo}
+% \begin{texample}[0.85]
+% |\actsymb{A}{\nthtop*{1}{x}:\angln}|
+% \producing
+% \rule{0pt}{12pt}$\actsymb{A}{\nthtop*{1}{x}:\angln}$
+% \end{texample}
+% \begin{texample}[0.85]
+% |\actsymb{A}{x:\nthtop*{1}{\angln}}|
+% \producing
+% \rule{0pt}{12pt}$\actsymb{A}{x:\nthtop*{1}{\angln}}$
+% \end{texample}
+% \begin{texample}[0.85]
+% |\actsymb{A}{\nthtop*{1}{x}y:\nthtop*{2}{\angln}}|
+% \producing
+% \rule{0pt}{12pt}$\actsymb{A}{\nthtop*{1}{x}y:\nthtop*{2}{\angln}}$
+% \end{texample}
+% \end{demo}
+% The optional argument \meta{length} changes the default spacing
+% for one symbol. The package also defines shortcuts for first,
+% second and third top precedence; see \autoref{sec:shortcuts}.
+% \end{DescribeMacro}
+% \end{DescribeMacro}
+%
+% \begin{DescribeMacro}{\nthbottom}
+% \begin{DescribeMacro}{\nthbottom*}
+% In the same vein as the above two commands,
+% \begin{quote}
+% \cmd{\nthbottom}\oarg{length}\marg{number}\marg{status} \\
+% \cmd{\nthbottom*}\oarg{length}\marg{number}\marg{status}
+% \end{quote}
+% put a precedence \meta{number} below a \meta{status}. With
+% \cmd{\nthbottom} the spacing between the status and the number is
+% a constant \cmd{\nthbottomsep}, whereas with \cmd{\nthbottom*}
+% enough spacing \cmd{\nthbottomskip} is left to bottom align the
+% precedence numbers. The |*| variant is most useful in cases
+% involving more than one bottom precedence numbers and statuses
+% with descenders.
+% \begin{demo}
+% \begin{texample}[0.85]
+% |\actsymb{A}{\nthtop{3}{x}%| \\
+% | \nthbottom{1}{y}\nthbottom{2}{z}}|
+% \producing
+% \rule{0pt}{12pt}$\actsymb{A}{\nthtop{3}{x}\nthbottom{1}{y}\nthbottom{2}{z}}$
+% \end{texample}
+% \begin{texample}[0.85]
+% |\actsymb{A}{\nthtop{3}{x}%| \\
+% | \nthbottom*{1}{y}\nthbottom*{2}{z}}|
+% \producing
+% \rule{0pt}{12pt}$\actsymb{A}{\nthtop{3}{x}\nthbottom*{1}{y}\nthbottom*{2}{z}}$
+% \end{texample}
+% \end{demo}
+% The optional argument \meta{length} changes the default spacing
+% for one symbol. The package also defines shortcuts for first,
+% second and third bottom precedence; see \autoref{sec:shortcuts}.
+% \end{DescribeMacro}
+% \end{DescribeMacro}
+%
+% \begin{rem}
+% The fact that top precedence numbers have zero height means they
+% will clash with a right superscript \fbox{\small IV}:
+% \begin{demo}
+% \begin{texample}[0.7]
+% |\actsymb{A}{\nthtop{1}{x}:\angln}[(m)]|
+% \producing
+% $\actsymb{A}{\nthtop{1}{x}:\angln}[(m)]$
+% \end{texample}

+% \section{Shortcuts}
+% \label{sec:shortcuts}
+%
+% Composing actuarial symbols from scratch using \cmd{\actsymb} can
+% easily get quite involved. For this reason, the package defines a
+% large number of shortcut macros to ease entry of the most common
+% symbols. We encourage authors to define their own shortcuts for
+% cases we did not consider. The package provides powerful facilities
+% to define shortcuts.
+%
+% \subsection{Basic symbols of life tables, insurance and annuities}
+% \label{sec:shortcuts:principal}
+%
+% \autoref{tab:principal} lists shortcuts to compose complete symbols
+% of life tables and benefits of insurance and annuities. For space
+% considerations only the mandatory arguments are given, but it should
+% be noted that all commands of \autoref*{tab:principal} accept the
+% optional arguments \meta{ll}, \meta{ul} and \meta{ur} of
+% \cmd{\actsymb}.
+%

+% \end{table}
+%
+% One will note that shortcuts for insurance benefits come in two
+% variants: one for the benefit payable at the end of the year of
+% death (standard shortcut) and one for the benefit payable at the
+% time of death (|*| variant). Shortcuts for annuity benefits have
+% three variants: payable at the end of the period (standard),
+% continuously (|*| variant) and at the beginning of the period (|**|
+% variant).
+%
+% \begin{DescribeMacro}{\@actinssc}
+% \begin{DescribeMacro}{\@actannsc}
+% \begin{DescribeMacro}{\@actothersc}
+% One may define additional shortcut macros similar to those of
+% \autoref{tab:principal} using the internal commands
+% \begin{quote}
+% |\@actinssc|\marg{symbol} \\
+% |\@actannsc|\marg{symbol} \\
+% |\@actothersc|\marg{symbol}
+% \end{quote}
+% Command |\@actinssc| automatically provides the two shortcuts for
+% insurance benefits, command |\@actannsc| provides the three
+% shortcuts for annuity benefits and command |\@actothersc|
+% provides a single shortcut for \meta{symbol}.
+%
+% For example, the package defines the shortcut \cmd{\px} with the
+% equivalent of %
+% ^^A below we abuse the texample environment to avoid defining
+% ^^A another environment just for this purpose
+% \begin{demo}
+% \begin{texample}[1]

+% \end{demo}
+% shortcuts \cmd{\Ax} and \cmd{\Ax*} with
+% \begin{demo}
+% \begin{texample}[1]
+% |\newcommand{\Ax}{\@actinssc{A}}| \producing
+% \end{texample}

+% \end{DescribeMacro}
+% \end{DescribeMacro}
+% \end{DescribeMacro}
+%
+% \begin{rem}
+% When used in the preamble of a document, the above commands need
+% to be protected by a |\makeatletter| \dots\ |\makeatother| pair
+% since they make use of the reserved character |@|. Therefore, to
+% define shortcuts, say, \cmd{\Bx} and \cmd{\Bx*} to the imaginary
+% benefits $B$ and $\bar{B}$, one would write in the preamble
+% \begin{demo}
+% \begin{texample}[1]

+% \subsection{Symbols for premiums, reserves and paid-up insurance}
+% \label{sec:shortcuts:premres}
+%
+% Symbols for premiums, reserves and paid-up insurance come in two
+% main variants: without an explicit benefit between parentheses for
+% insurances payable at the end of the year of death, and with the
+% type of benefit specified for all other insurances and annuities.
+%
+% \autoref{tab:premres} lists two sets of shortcuts to compose symbols
+% for premiums, reserves and paid-up insurance. Shortcuts from the
+% first set take in mandatory argument the content of the \meta{lr}
+% subscript of actuarial symbols. Those from the second set require a
+% complete benefit symbol in argument. One may use the shortcuts of
+% \autoref{tab:principal} to this effect. Again, only the mandatory
+% arguments are given in the table, but all commands accept the
+% optional arguments \meta{ll}, \meta{ul} and \meta{ur} of
+% \cmd{\actsymb}.

+% \section{Package options}
+% \label{sec:options}
+%
+% The package offers two options to control the placement of
+% precedence numbers:
+% \begin{description}
+% \item[\mdseries\ttfamily alignpreced] always align top and bottom
+% precedence numbers; makes \cmd{\nthtop} and \cmd{\nthbottom}
+% equivalent to \cmd{\nthtop*} and \cmd{\nthbottom*},
+% respectively;
+% \item[\mdseries\ttfamily compactpreced] always put precedence
+% numbers close to the corresponding status; makes \cmd{\nthtop*}
+% and \cmd{\nthbottom*} equivalent to \cmd{\nthtop} and
+% \cmd{\nthbottom}, respectively.
+% \end{description}
+% Option |alignpreced| can be useful to simplify entry of uniformly
+% positioned precedence numbers. On the other hand, option
+% |compactpreced| is merely included as a complement to |alignpreced|.
+% We do not recommended --- nor see a reason --- to use it as it
+% basically renders inoperative commands \cmd{\nthtop*} and
+% \cmd{\nthbottom*}.

+% \newpage
+% \section{Comprehensive life contingencies symbol list}
+% \label{sec:comprehensive}
+%
+% This appendix was inspired by \citet{Trivedi:lifecon:2004}. The
+% title is a nod to the immensely useful \emph{Comprehensive
+% {\LaTeX} Symbol List} of \citet{comprehensive}.
+%
+% The table below contains all the life contingencies symbols listed
+% in Appendix~3 of \citet{Bowers:2e:1997} along with the code to
+% compose them with \pkg{actuarialsymbol} (and therefore
+% \pkg{actuarialangle}) loaded. Often times there are various ways to
+% obtain a symbol; we tried to always present the most compact and
+% legible option. Not all symbols require features of
+% \pkg{actuarialsymbol}.
+%
+% Calligraphic letters are typeset using \cmd{\mathcal}. The specific
+% versions of $\mathcal{L}$ and $\mathcal{D}$ that appear in this
+% table require package \pkg{rsfso} \citep{rsfso}, which is \emph{not}
+% loaded by \pkg{actuarialsymbol}. Standard versions of the
+% calligraphic letters are $\text{\usefont{OMS}{zplm}{m}{n} L}$ and
+% $\text{\usefont{OMS}{zplm}{m}{n} D}$. See Table~299 of
+% \citet{comprehensive} for other options.

+% \subsection{Required packages}
+% \label{sec:implementation:packages}
+%
+% \begin{macro}{RequirePackage}
+% The package depends on packages \pkg{amsmath} \citep{amsmath} and
+% \pkg{actuarialangle} \citep{actuarialangle}.
+% \begin{macrocode}
+\RequirePackage{amsmath}
+\RequirePackage{actuarialangle}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Package options}
+% \label{sec:implementation:options}
+%
+% \begin{macro}{\ifacts@alignpreced}
+% \begin{macro}{\ifacts@acompactpreced}
+% We define two flags to keep track of the type of alignment for
+% precedence numbers. Both are false by default.
+% \begin{macrocode}
+\newif\ifacts@alignpreced \acts@alignprecedfalse
+\newif\ifacts@compactpreced \acts@compactprecedfalse
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \begin{macro}{\DeclareOption}
+% Declaration of the package options and processing.
+% \begin{macrocode}
+\DeclareOption{alignpreced}{\acts@alignprecedtrue}
+\DeclareOption{compactpreced}{\acts@compactprecedtrue}
+\ProcessOptions
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Actuarial symbol}
+% \label{sec:implementation:actsymb}
+%
+% We face three main challenges when trying to compose actuarial
+% symbols: position a subscript and a superscipt to the left of a main
+% symbol; ensure that the left and right subscripts and superscripts
+% are vertically aligned; maintain consistency with the placement of
+% subscripts and superscripts elsewhere in the document.
+%
+% \subsubsection{User level and parsing commands}
+% \label{sec:implementation:actsymb:user}
+%
+% \begin{macro}{actsymb}
+% We first define the user level command.
+% \begin{macrocode}
+\DeclareRobustCommand{\actsymb}{\acts@actsymb}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\acts@actsymb}
+% \begin{macro}{\acts@@actsymb}
+% \begin{macro}{\acts@@@actsymb}
+% \begin{macro}{\acts@@@@actsymb}
+% With its unusual syntax, \cmd{\actsymb} requires four parsing
+% macros to pass the arguments to the actual workhorse
+% \cmd{\@actsymbol}.
+% \begin{macrocode}
+\newcommand\acts@actsymb{%
+ \@ifnextchar[{\acts@@actsymb}%
+ {\acts@@actsymb[]}}
+\newcommand\acts@@actsymb{}
+\def\acts@@actsymb[#1]{%
+ \@ifnextchar[{\acts@@@actsymb[#1]}%
+ {\acts@@@actsymb[#1][]}}
+\newcommand\acts@@@actsymb{}
+\def\acts@@@actsymb[#1][#2]{%
+ \@ifnextchar[{\acts@@@@actsymb[#1][#2]}%
+ {\acts@@@@actsymb[#1][#2][]}}
+\newcommand\acts@@@@actsymb{}
+\def\acts@@@@actsymb[#1][#2][#3]#4#5{%
+ \@ifnextchar[{\@actsymbol[#1][#2][#3]{#4}{#5}}%
+ {\@actsymbol[#1][#2][#3]{#4}{#5}[]}}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Symbol construction}
+% \label{sec:implementation:actsymb:workhorse}
+%
+% \begin{macro}{\@actsymbol}
+% We now define the workhorse to compose an actuarial symbol
+% allowing for auxiliary symbols on all four corners around a
+% principal symbol. The macro \cmd{\@actsymbol} has the following
+% six arguments, using the notation from of the schematics
+% representations \eqref{schema1} and \eqref{schema2}:
+% \begin{enumerate}[nosep]
+% \item lower left subscript \fbox{\small I}; may be empty;
+% \item upper left superscript \fbox{\small II}; may be empty;
+% \item principle symbol $P$; when empty a standard symbol is
+% typeset;
+% \item principal symbol $S$; assumed present;
+% \item lower right subscript \fbox{\small III}; assumed present;
+% \item upper right superscript \fbox{\small IV}; may be empty.
+% \end{enumerate}
+% The definition below is heavily inspired by the code of
+% \cmd{\prescript} from package \pkg{mathtools} \citep{mathtools}
+% which, as reported by the author, is itself based on a posting to
+% |comp.text.tex| by Michael J.~Downes. Some of the comments below
+% are still his.
+% \begin{macrocode}
+\def\@actsymbol[#1][#2][#3]#4#5[#6]{
+% \end{macrocode}
+% We put the principle symbol and all subscripts and superscript into
+% horizontal boxes using \cmd{\@mathmeasure} of package \pkg{amsmath}.
+% \begin{macrocode}
+ \@mathmeasure\z@\displaystyle{#3}
+ \@mathmeasure\@ne\scriptstyle{#1}
+ \@mathmeasure\tw@\scriptstyle{#2}
+ \@mathmeasure\thr@@\scriptstyle{#5}
+ \@mathmeasure4\scriptstyle{#6}
+% \end{macrocode}
+% Do not let a preceding mathord symbol approach without any
+% intervening space.
+% \begin{macrocode}
+ \mathord{}
+% \end{macrocode}
+% Right align the left subscript and superscript (if there is a
+% superscript) by adjusting the width of their horizontal boxes.
+% \begin{macrocode}
+ \ifdim \wd\tw@>\z@ \ifdim \wd\tw@>\wd\@ne
+ \setbox\@ne\hbox to\wd\tw@{\hfil\unhbox\@ne}
+ \else
+ \setbox\tw@\hbox to\wd\@ne{\hfil\unhbox\tw@}
+ \fi\fi
+% \end{macrocode}
+% Bottom align the left and right subscripts by making their heights
+% equal.
+% \begin{macrocode}
+ \ifdim \ht\@ne>\ht\thr@@
+ \ht\thr@@=\ht\@ne
+ \else
+ \ht\@ne=\ht\thr@@
+ \fi
+% \end{macrocode}
+% Actual symbol construction. First the case where there is at least
+% one superscript (the nested conditionals emulate an OR condition).
+% \begin{macrocode}
+ \ifnum\ifdim \wd\tw@>\z@ 1\else\ifdim \wd4>\z@ 1\else 0\fi\fi
+ =1
+% \end{macrocode}
+% To ensure equal spacing with the subscripts on both sides of the
+% principal symbol, make the depths of the left and right
+% supercripts equal.
+% \begin{macrocode}
+ \ifdim \dp\tw@>\dp4 \dp4=\dp\tw@\else \dp\tw@=\dp4\fi
+% \end{macrocode}
+% Typesetting of the left subscript and superscript. Use
+% \cmd{\mathopen} to suppress space between those and the principal
+% symbol even when the latter is not of type ord.
+% \begin{macrocode}
+ \mathopen{\vphantom{#4}^{\box\tw@}\sb{\box\@ne}}%
+% \end{macrocode}
+% Typesetting of the principal symbol and the right subscript and
+% superscript. The principal symbol is either a principal symbol alone
+% or a principle symbol and a benefit symbol between parentheses. In
+% the latter case, we make sure to align the subscripts and
+% superscripts only around de principle symbol.
+% \begin{macrocode}
+ \ifdim\wd\z@=\z@
+ #4^{\box4}\sb{\box\thr@@}%
+ \else
+ #3^{\box4}\sb{\vphantom{\copy\thr@@}}(#4\sb{\box\thr@@})%
+ \fi
+ \else
+% \end{macrocode}
+% Same ideas as above in the simpler case without superscripts. That
+% way, {\TeX}'s default placement of subscripts and superscripts is
+% maintained.
+% \begin{macrocode}
+ \mathopen{\vphantom{#4}\sb{\box\@ne}}%
+ \ifdim\wd\z@=\z@
+ #4\sb{\box\thr@@}%
+ \else
+ #3(#4\sb{\box\thr@@})%
+ \fi
+ \fi
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Shortcuts for basic symbols of life tables, insurance and annuities}
+% \label{sec:implementation:actsymb:principalsc}
+%
+% \begin{macro}{\@actinssc}
+% \begin{macro}{\@actannsc}
+% \begin{macro}{\@actothersc}
+% We first define the internal macros and parsing macros used to
+% define shortcuts for insurance benefits (\cmd{\@actinssc}),
+% annuity benefits (\cmd{\@actannsc}) and simple symbols
+% (\cmd{\@actothersc}).
+% \begin{macrocode}
+\newcommand\@actinssc[1]{%
+ \@ifstar{\acts@actsc{\bar{#1}}}%
+ {\acts@actsc{#1}}}
+\newcommand\@actannsc[1]{%
+ \@ifstar{\@ifstar{\acts@actsc{\ddot{#1}}}%
+ {\acts@actsc{\bar{#1}}}}
+ {\acts@actsc{#1}}}
+\newcommand\acts@actsc[1]{%
+ \@ifnextchar[{\acts@@actsc{#1}}%
+ {\acts@@actsc{#1}[]}}
+\let\@actothersc\acts@actsc
+\newcommand\acts@@actsc{}
+\def\acts@@actsc#1[#2]{%
+ \@ifnextchar[{\acts@@@actsc{#1}[#2]}%
+ {\acts@@@actsc{#1}[#2][]}}
+\newcommand\acts@@@actsc{}
+\def\acts@@@actsc#1[#2][#3]#4{%
+ \@ifnextchar[{\@actsymbol[#2][#3][]{#1}{#4}}%
+ {\@actsymbol[#2][#3][]{#1}{#4}[]}}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \begin{macro}{\DeclareRobustCommand}
+% We can now define all the shortcuts of \autoref{tab:principal}.
+% \begin{macrocode}
+\DeclareRobustCommand{\lx}{\@actothersc {\ell}}
+\DeclareRobustCommand{\Lx}{\@actothersc {\mathcal{L}}}
+\DeclareRobustCommand{\dx}{\@actothersc d}
+\DeclareRobustCommand{\Dx}{\@actothersc{\mathcal{D}}}
+\DeclareRobustCommand{\px}{\@actothersc p}
+\DeclareRobustCommand{\qx}{\@actothersc q}
+\DeclareRobustCommand{\Ax}{\@actinssc A}
+\DeclareRobustCommand{\Ex}{\@actinssc E}
+\DeclareRobustCommand{\ax}{\@actannsc a}
+\DeclareRobustCommand{\sx}{\@actannsc s}
+\DeclareRobustCommand{\aringx}{\@actothersc{\mathring{a}}}
+\DeclareRobustCommand{\eringx}{\@actothersc{\mathring{e}}}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Shortcuts for premiums, reserves and paid-up insurance}
+% \label{sec:implementation:actsymb:premressc}
+%
+% \begin{macro}{\@actpremres}
+% Not unlike above, we first define the internal and parsing macros
+% used to create shortcut for premiums, reserves and paid-up insurance
+% symbols.
+% \begin{macrocode}
+\newcommand\@actpremres[1]{%
+ \@ifstar{\acts@actpremres{\bar{#1}}}%
+ {\acts@actpremres{#1}}}
+\newcommand\acts@actpremres[1]{%
+ \@ifnextchar[{\acts@@actpremres{#1}}%
+ {\acts@@actpremres{#1}[]}}
+\newcommand\acts@@actpremres{}
+\def\acts@@actpremres#1[#2]{%
+ \@ifnextchar[{\acts@@@actpremres{#1}[#2]}%
+ {\acts@@@actpremres{#1}[#2][]}}
+\newcommand\acts@@@actpremres{}
+\def\acts@@@actpremres#1[#2][#3]#4{%
+ \@ifnextchar[{\@actsymbol[#2][#3][#1]{{#4}}{}}%
+ {\@actsymbol[#2][#3][#1]{{#4}}{}[]}}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\DeclareRobustCommand}
+% Then we can define the shortcuts of \autoref{tab:premres}.
+% \begin{macrocode}
+\DeclareRobustCommand{\Px}{\@actothersc P}
+\DeclareRobustCommand{\Vx}{\@actothersc V}
+\DeclareRobustCommand{\Wx}{\@actothersc W}
+\DeclareRobustCommand{\premium}{\@actpremres P}
+\DeclareRobustCommand{\reserve}{\@actpremres V}
+\DeclareRobustCommand{\paidup}{\@actpremres W}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Shortcuts for auxiliary symbols}
+% \label{sec:implementation:actsymb:auxsc}
+%
+% \begin{macro}{\DeclareRobustCommand}
+% Here we define the shortcuts for common auxiliary symbols listed in
+% \autoref{tab:aux}. Command \cmd{\joint} is simply defined as an
+% alias of \cmd{\overline}.
+% \begin{macrocode}
+\DeclareRobustCommand{\term}[2]{\itop{#1}:\angl{#2}}
+\DeclareRobustCommand{\termxn}{{\itop{x}:\angln}}
+\DeclareRobustCommand{\pureendow}[2]{#1:\itop{\angl{#2}}}
+\DeclareRobustCommand{\pureendowxn}{{x:\itop{\angln}}}
+\DeclareRobustCommand{\endow}[2]{#1:\angl{#2}}
+\DeclareRobustCommand{\endowxn}{{x:\angln}}
+\let\joint\overline
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Two-letter symbols}
+% \label{sec:implementation:twoletsymb}
+%
+% \begin{macro}{\twoletkern}
+% \begin{macro}{\twoletsymb}
+% The definition of the user level command \cmd{\twoletsymb} is
+% pretty straighforward.
+% \begin{macrocode}
+\newlength{\twoletkern}
+\setlength{\twoletkern}{1.2pt}
+\DeclareRobustCommand{\twoletsymb}[3][\twoletkern]{(#2\kern-#1#3)}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \begin{macro}{\@twoletinssc}
+% \begin{macro}{\@twoletannsc}
+% Following the same lines as above, we define two internal macros

+% \subsection{Precedence numbers}
+% \label{sec:implementation:preced}
+%
+% The system of precedence numbers builds on a backbone that used to
+% be part of package \pkg{actuarialangle}. The author of the code is
+% unknown. Some of the comments on \cmd{\@precendence}, below, are his
+% or hers.
+%
+% \subsubsection{User level lengths and commands}
+% \label{sec:implementation:preced:user}
+%
+% \begin{macro}{\nthtopsep}
+% \begin{macro}{\nthtopskip}
+% \begin{macro}{\nthbottomsep}
+% \begin{macro}{\nthbottomskip}
+% Let us start by defining the lengths needed to position the
+% precedence numbers above or below the statuses.
+% \begin{macrocode}
+\newlength{\nthtopsep}
+\setlength{\nthtopsep}{2\p@}
+\newlength{\nthtopskip}
+\setlength{\nthtopskip}{7\p@}
+\newlength{\nthbottomsep}
+\setlength{\nthbottomsep}{2\p@}
+\newlength{\nthbottomskip}
+\setlength{\nthbottomskip}{9\p@}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \begin{macro}{\nthtop}
+% \begin{macro}{\nthbottom}
+% Next up are the two user level commands and the internal commands
+% that call the workhorse \cmd{\@precedence}.
+% \begin{macrocode}
+\DeclareRobustCommand{\nthtop}{\@ifstar\@varnthtop\@nthtop}
+\DeclareRobustCommand{\nthbottom}{\@ifstar\@varnthbottom\@nthbottom}
+\newcommand{\@nthtop}[3][\nthtopsep]{%
+ \mathpalette{\@precedence t\z@{#1}{#2}}{#3}}
+\newcommand{\@varnthtop}[3][\nthtopskip]{%
+ \mathpalette{\@precedence t{#1}\z@{#2}}{#3}}
+\newcommand{\@nthbottom}[3][\nthbottomsep]{%
+ \mathpalette{\@precedence b\z@{#1}{#2}}{#3}}
+\newcommand{\@varnthbottom}[3][\nthbottomskip]{%
+ \mathpalette{\@precedence b{#1}\z@{#2}}{#3}}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\@nthtop}
+% \begin{macro}{\@nthbottom}
+% With the internal commands defined we can now process the package
+% options. Option |alignpreced| makes the internal macros
+% \cmd{\@nthtop} and \cmd{\@nthbottom} equivalent to
+% \cmd{\@varnthtop} and \cmd{\@varnthbottom}, respectively.
+% \begin{macrocode}
+\ifacts@alignpreced
+ \let\@nthtop\@varnthtop
+ \let\@nthbottom\@varnthbottom
+\fi
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \begin{macro}{\@varnthtop}
+% \begin{macro}{\@varnthbottom}
+% Option |compactpreced| does the opposite.
+% \begin{macrocode}
+\ifacts@compactpreced
+ \let\@varnthtop\nthtop
+ \let\@varnthbottom\nthbottom
+\fi
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Number and status positioning}
+% \label{sec:implementation:preced:workhorse}
+%
+% \begin{macro}{\@precedence}
+% We now define the workhorse to position precedence numbers above
+% or below statuses, smashed so that the height of the auxiliary
+% symbol containing the call remains unaffected. The macro
+% \cmd{\@precedence} has the following six arguments:
+% \begin{enumerate}[nosep]
+% \item |t| for top or |b| for bottom;
+% \item baseline skip between the top and bottom symbols;
+% \item spacing between the top and bottom symbols;
+% \item first argument from the user;
+% \item one of math style selecting commands (\cmd{\displaystyle},
+% \cmd{\textstyle}, \cmd{\scriptstyle}, \cmd{\scriptscriptstyle})
+% from \cmd{\mathpalette};
+% \item second argument given by the user.
+% \end{enumerate}
+% This peculiar ordering of the arguments is done to work around the
+% restriction of \cmd{\mathpalette} that it only reads two
+% arguments.
+% \begin{macrocode}
+\def\@precedence#1#2#3#4#5#6{%
+ \setbox\tw@\hbox{$\m@th#5#4$}%
+ \setbox\z@\hbox{$\m@th#5#6$}
+ \dimen@\wd\z@
+ \vbox to\ht\z@{%
+ \baselineskip=#2
+ \lineskip=#3
+ \lineskiplimit\lineskip
+ \if b#1\relax\box\z@\else\vss\fi
+ \hbox to\dimen@{\hss\unhbox\tw@\hss}%
+ \if t#1\relax\box\z@\else\vss\fi
+ }
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Shortcuts and aliases}
+% \label{sec:implementation:preced:shortcuts}
+%
+% \begin{macro}{\DeclareRobustCommand}
+% We finish off by defining the shortcuts and aliases of
+% \autoref{tab:preced}.
+% \begin{macrocode}
+\DeclareRobustCommand{\firsttop}{%
+ \@ifstar{\@varnthtop{1}}{\@nthtop{1}}}
+\DeclareRobustCommand{\secondtop}{%
