+This package defines a single command \actuarialangle to typeset nice
+looking "angles" in present value of an annuity symbols common in
+actuarial and financial notation.
+
+LICENCE
+
+Public Domain
+
+AUTHOR
+
+The code in this package was given to me (Vincent Goulet
+<vincent.goulet@act.ulaval.ca>) by a former colleague who would simply
+copy it in the preamble of all his documents needing an "angle"
+symbol. The actual author of the code is unknown.
+
+My sole contribution was to make a package out of the code.
+
+USAGE
+
+Copy the package file "where LaTeX can find it", then
+
+  \usepackage{actuarialangle}
+
+and (in math mode)
+
+  \actuarialangle{n}
+
+to typeset "angle n". For a complete present value symbol, use
+something like 
+
+  a_{\actuarialangle{n}}
+
+SHORTCUTS
+
+You will most likely want to use the following shortcuts:
+
+\angl  for \actuarialangle
+\angln for \angl{n}
+\anglr for \angl{r}

+\def\actuarialangle{\mathpalette\act@angle}
+%
+% The operation of \mathpalette causes \actuarialangle{30} to expand
+% to a mathchoice. This ensures that proper sizing will be done if
+% \angle is ever used outside of a first-level subscript:
+%
+% \mathchoice{%
+% {\act@angle\displaystyle{30}}%
+% {\act@angle\textstyle{30}}%
+% {\act@angle\scriptstyle{30}}%
+% {\act@angle\scriptscriptstyle{30}}%
+% }
+%
+\def\act@angle#1#2{%
+\mathord{%
+\mkern1mu % Add a bit of preceding space
+\vbox{\hrule \hbox{\vbox{%
+% This amount of vertical space is the normal space for \overline in a
+% subscript:
+\kern3\fontdimen8\scriptfont\thr@@
+\hbox{$#1#2\m@th$}}%
+% Make the right-hand rule extend down to the depth of a parenthesis
+% even if the symbol under the angle does not have a descender:
+\setbox\z@\hbox{$#1()$}\vrule depth\dp\z@}}%
+\mkern1mu}% Add a bit of following space 
+}% end \act@angle
+%
+% \topprecedence puts a precedence number above an item, smashed so
+% that the apparent height of the item is its normal height.
+%
+\def\topprecedence#1#2{\mathpalette{\preced@ t{}{#1}}{#2}}
+%
+% Put a multiplier in the empty set of braces to increase
+% the spacing between the precedence number and the
+% symbol to which it applies, e.g.
+%
+% \def\topprecedence#1#2{\mathpalette{\preced@ t{2.5}{#1}}{#2}}
+%
+% This also applies for \botprecedence and \vartopprecedence.
+% If it is desired that all precedence numbers fall at the
+% same height, regardless of whether there is an hrule between
+% them and the symbol to which they apply, then make
+% \topprecedence the same as \vartopprecedence.
+%
+\def\botprecedence#1#2{\mathpalette{\preced@ b{}{#1}}{#2}}
+%
+% \vartopprecedence provides extra space below the top
+% symbol, to accommodate an intervening hrule.
+%
+\def\vartopprecedence#1#2{\mathpalette{\preced@ t3{#1}}{#2}}
+%
+% In \preced@, #1 is `t' for top or `b' for bottom, #2 is a
+% multiplier for the space between the top and bottom symbols (may
+% be empty), #3 is the first argument from the user, #4 is
+% \displaystyle or \textstyle or \scriptstyle or
+% \scriptscriptstyle, from \mathpalette, and #5 is the second
+% argument given by the user. This peculiar ordering of the
+% arguments is done to work around the restriction of \mathpalette
+% that it only reads 2 arguments.
+%
+\def\preced@#1#2#3#4#5{%
+% Measure the arguments:
+\setbox\tw@\hbox{$\m@th#4#3$}%
+\setbox\z@\hbox{$\m@th#4#5$}\dimen@\wd\z@
+\vbox{% to\ht\z@{%
+\baselineskip\z@skip
+% \lineskip is set using AMSTeX's \ex@, if available, for a slight
+% refinement in the spacing if this macro is used in eightpoint
+% text. If \ex@ is not available, \p@ is used.
+\lineskip#2\ifx\UNDEFINED\ex@\p@\else\ex@\fi\relax

+\if b#1\relax\box\z@\else\vss\fi
+\hbox to\dimen@{\hss\unhbox\tw@\hss}%

+}% end \vbox
+}% end \preced@
+% Restore the category code of the @ character:
+\catcode`\@=11
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%To get a little more space after stuff under the angle, define \angl 
+% in the following way:
+%
+\def\angl#1{{\actuarialangle{{#1}\mkern2mu}}}
+%
+%
+\def\angln{{\angl n}}
+%
+\def\anglr{{\angl r}}
+%
+\def\lift#1#2{{\topprecedence{#1}{#2}}}
