+%\section{Introduction}
+%
+% This little \LaTeX\ package implements the macro
+% \DescribeMacro{\athnum}
+% |\athnum|. The macro transforms an Arabic numeral, i.e., the kind
+% of numerals we all use (e.g., 1, 5, 789 etc), to the corresponding
+% {\itshape Athenian} numeral. Athenian numerals were in use only in
+% ancient Athens.
+% The special multiples, which the system employs, are drawn
+% \DescribeMacro{\PiIt} with the special macro |\PiIt|. The macro
+% produces a more or less $\Pi$-like shape above a letter.
+%
+%\section{The Numbering System}
+%
+% The athenian numbering system, like the roman one, employs
+% letters to denote important numbers. Multiple occurrence of a letter denote
+% a multiple of the ``important'' number, e.g., the letter I denotes 1, so
+% III denotes 3. Here are the basic digits used in the Athenian numbering
+% system:
+% \begin{itemize}
+% \item I denotes the number one (1)
+% \item $\Pi$ denotes the number five (5)
+% \item $\Delta$ denotes the number ten (10)
+% \item H denotes the number one hundred (100)
+% \item X denotes the number one thousand (1000)
+% \item M denotes the number ten thousands (10000)
+%\end{itemize}
+% Moreover, the letters $\Delta$, H, X, and M under the letter $\Pi$,
+% denote five times their original value, e.g., the symbol
+% \PiIt{X}, denotes the number 5000, and the symbol
+% \PiIt{$\Delta$}, denotes the number 50. It must be noted that
+% the numbering system does not provide negative numerals or a symbol for
+% zero.
+%
+% The Athenian numbering system is described, among others, in an article in
+% Encyclopedia $\Delta o\mu\acute{\eta}$, Vol. 2, page 280, 7th edition,
+% Athens, October 2, 1975.
+%
+% \section{The Code}
+% Before we do anything further, we have to identify the package.
+% \StopEventually
+%
+% \begin{macrocode}
+%<*package>
+\ProvidesPackage{grnumalt}[1997/09/19\space v1.1]
+\typeout{Package: `grnumalt' v1.0\space <1997/09/19> (AS)}
+% \end{macrocode}
+%
+%\begin{macro}{\PiIt}
+% It is very important to be able to correctly typeset the multiples of
+% the numbering system. For this purpose we define the macro |\PiIt|. The
+% macro uses two ``length'' variables.
+% \begin{macrocode}
+\newdimen\@boxW \newdimen\@boxH
+% \end{macrocode}
+% We make the |\PiIt| macro a robust command.
+% \begin{macrocode}
+\DeclareRobustCommand{\PiIt}[1]{%
+% \end{macrocode}
+% In order to correctly produce the $\Pi$ symbol we need to know the
+% height and width of the letter that goes under a $\Pi$. This is done by
+% using the standard \LaTeX\ macros: |\settowidth| and |\settoheight|.
+% \begin{macrocode}
+ \settowidth{\@boxW}{#1}%
+ \settoheight{\@boxH}{#1}%
+% \end{macrocode}
+% Since, the width of an ordinary rule is 0.4 pt we must add 0.8 pt to
+% the width of the letter.
+% \begin{macrocode}
+ \addtolength{\@boxW}{0.8pt}
+% \end{macrocode}
+% Now comes the interesting part: the actual drawing. We create a vertical
+% box. Inside this box we draw a horizontal rule of width equal to
+% the width of the letter. Next, we create a horizontal box in order to
+% make the vertical lines. We draw the first vertical line, then we put
+% the letter in a |\mbox|, since it may be a mathematical
+% symbol\footnote{greek letters are considered mathematical symbols
+% by \TeX.}. After the |\mbox| we draw the second vertical line and we
+% ``close'' the horizontal box. A little white space is put after the vertical
+% box, so that adjacent multiplies do not look ugly!
+% \begin{macrocode}
+ \vbox{%
+ \hrule width\@boxW\hbox{%
+ \vrule height\@boxH\mbox{#1}%
+ \vrule height\@boxH}}\kern.5pt}
+% \end{macrocode}
+%\end{macro}
+%\begin{macro}{\athnum}
+% Now, we turn our attention to the definition of the macro
+% |\athnum|. This macro uses one integer variable.
+% \begin{macrocode}
+\newcount\@ath@num
+% \end{macrocode}
+% The macro |\athnum| is also defined as a robust command.
+% \begin{macrocode}
+\DeclareRobustCommand{\athnum}[1]{%
+% \end{macrocode}
+% The macro does not work in math mode so we must ensure that it will not
+% be used in math mode. We could use |\ensuremath|, but our definition
+% is too long...
+% \begin{macrocode}
+ \ifmmode
+ \errhelp{^^J This macro has been defined to work^^J
+ *only* in non-math mode. It is definitely^^J
+ sure that you are using it in math mode.^^J}%
+ \errmessage{^^JYou can't use macro atheniannumeral^^J
+ in math mode.^^J}%
+% \end{macrocode}
+% If we are not in math mode, we can start computing the Athenian numeral.
+% After assigning to variable |\@ath@num| the value of the macro's argument, we
+% make sure that the argument is in the expected range, i.e., it is greater
+% than zero. In case it isn't we simply produce a |\space|, warn the user
+% about it and quit.
+% \begin{macrocode}
+ \else\@ath@num#1\relax
+ \ifnum\@ath@num=\z@%
+ \space%
+ \PackageWarning{grnumalt}{%
+ Illegal value (\the\@ath@num) for athenian numeral}%
+ \else\ifnum\@ath@num<\z@%
+ \space%
+ \PackageWarning{grnumalt}{%
+ Illegal value (\the\@ath@num) for athenian numeral}%
+ \else$
+% \end{macrocode}
+% Having done all the necessary checks, we are now ready to do the actual
+% computation. If the number is greater than $49999$, then it certainly
+% has at least one \PiIt{M} ``digit''. We find all such digits by continuously
+% subtracting $50000$ from |\NumA|, until |\NumA| becomes less than
+% $50000$.
+% \begin{macrocode}
+ \loop\ifnum\@ath@num>49999
+ \PiIt{$\mathrm{M}$}
+ \advance\@ath@num-50000
+ \repeat
+% \end{macrocode}
+% We now check for tens of thousands.
+% \begin{macrocode}
+ \loop\ifnum\@ath@num>9999
+ \mathrm{M}\advance\@ath@num-\@M
+ \repeat
+% \end{macrocode}
+% Since a number can have only on \PiIt{X} ``digit'' (equivalent to 5000), it
+% is easy to check it out and produce the corresponding numeral in case it does
+% have one.
+% \begin{macrocode}
+ \ifnum\@ath@num>4999
+ \PiIt{$\mathrm{X}$}
+ \advance\@ath@num-5000
+ \fi
+% \end{macrocode}
+% Next, we check for thousands, the same way we checked for tens of thousands.
+% \begin{macrocode}
+ \loop\ifnum\@ath@num>999
+ \mathrm{X}\advance\@ath@num-\@m
+ \repeat
+% \end{macrocode}
+% Like the five thousands, a numeral can have at most one \PiIt{H} ``digit''
+% (equivalent to 500).
+% \begin{macrocode}
+ \ifnum\@ath@num>499
+ \PiIt{$\mathrm{H}$}
+ \advance\@ath@num-500
+ \fi
+% \end{macrocode}
+% It is time to check hundreds, which follow the same pattern as thousands
+% \begin{macrocode}
+ \loop\ifnum\@ath@num>99
+ \mathrm{H}\advance\@ath@num-100
+ \repeat
+% \end{macrocode}
+% A numeral can have only one \PiIt{$\Delta$} ``digit'' (equivalent to 50).
+% \begin{macrocode}
+ \ifnum\@ath@num>49
+ \PiIt{$\Delta$}
+ \advance\@ath@num-50
+ \fi
+% \end{macrocode}
+% Let's check now decades.
+% \begin{macrocode}
+ \loop\ifnum\@ath@num>9
+ \Delta\advance\@ath@num by-10
+ \repeat
+% \end{macrocode}
+% We check for fives and, finally, for the digits 1, 2, 3, and 4.
+% \begin{macrocode}
+ \ifnum\@ath@num>4
+ \Pi
+ \advance\@ath@num-5
+ \fi
+ \ifcase\@ath@num
+ \or\mathrm{I}
+ \or\mathrm{II}
+ \or\mathrm{III}
+ \or\mathrm{IIII}
+ \fi$
+ \fi\fi\fi}
+% \end{macrocode}
+% \DescribeMacro{\@athnum} The command |\@athnum| is defined just to make
+% it possible to have, e.g., page numbering with athenian numerals.
