% \section{Introduction}
%
% Twelve of the fifteen members of the European Union have agreed
% to replace their national currencies by a common currency, the
% \emph{Euro}. Before the 1\textsuperscript{st} of January 2001 the Euro was only a
% unit for calculations, with fixed conversion rates for
% each of the old currencies. Since then the Euro is actual money with
% coins and bank notes. The Francs, the D-Mark, the Schilling,
% they are history.
% Several further countries will join the European Union over
% the next years, and sooner or later also the so-called \emph{Euro-zone}.
% It's still common practice in Europe to write monetary amounts both in the national
% currency and in the new \euro~currency,
% thus helping to become familiar with the \emph{Euro}.
%
% But it's a nuisance to convert every value by hand or even with
% a calculator. Let our computers do all the hard work.
% Although \TeX\ is unable to do such calculations with
% its basic arithmetic functions, there's a way out: The |fp| package
% allows to deal with numbers ranging from
% \(-999999999999999999{,}999999999999999999\) to
% \(+999999999999999999{,}999999999999999999\) with high precision.
%
% Since there are so many currencies and different possible formats,
% this package provides only a customizable interface. All parameters are
% predefined in a common way, though, so that no further definitions will be
% necessary in most cases. The package tries to load an optional file
% `|euro.cfg|' where such local customizing commands may be placed in
% (see section~\ref{sec:config} for further explanation).
%
%
%
%
%
% \section{How to use the package}
%
% \subsection{The main macro}
%
% The \DescribeMacro{\EURO}|\EURO| command does the main work.
% It takes the \textit{source currency unit,} an optional \textit{destination currency unit,}
% both as three-digits \textsc{ISO} currency codes (see table \ref{tab:iso}), and
% the respective \emph{money amount}.
%
% \begin{syntax}
% |\EURO{|\<source currency unit>|}[|\<destination currency unit>|]{|\<amount>|}|
% \end{syntax}
%
%
% \begin{table}
% \begin{quote}
% \begin{center}
% \begin{tabular}{ll@{\hspace{2cm}}ll}
% \texttt{EUR}& Europe&    \texttt{GRD}& Greece\\
% \texttt{ATS}& Austria&   \texttt{IEP}& Ireland\\
% \texttt{BEF}& Belgium&   \texttt{ITL}& Italy\\
% \texttt{DEM}& Germany&   \texttt{LUF}& Luxembourg\\
% \texttt{ESP}& Spain&     \texttt{NLG}& The Netherlands\\
% \texttt{FIM}& Finland&  \texttt{PTE}& Portugal\\
% \texttt{FRF}& France
% \end{tabular}
%
% \caption{ISO currency codes of the \emph{Euro} and of the twelve \emph{Euro-zone} countries.}
% \label{tab:iso}
% \end{center}
% \end{quote}
% \end{table}
%
% A dot is to be used as \emph{decimal `point'} separating a number's integer and
% fractional part. Numbers may of course be negative.
% If the optional destination currency unit is omitted, the \emph{Euro} is taken.
%
% \begin{example}
% |\EURO{BEF}[FIM]{70}|&  \EURO{BEF}[FIM]{70}\\
% |\EURO{FIM}[BEF]{70}|&  \EURO{FIM}[BEF]{70}\\
% |\EURO{BEF}[BEF]{70}|&  \EURO{BEF}[BEF]{70}\rlap{\hspace{3.5em}[surprised?]}\\
% |\EURO{FIM}{17.8}|&     \EURO{FIM}{17.8}
% \end{example}
% \null
%
%
%
%
% \subsection{How to change the local style}
%
% The ISO currency codes don't really look good in running text. You
% can replace them by some other currency symbol or tag using the
% \DescribeMacro{\EUROSYM}|\EUROSYM| command.
%
% \begin{syntax}
% |\EUROSYM{|\<currency unit>|}{|\<symbol>|}|
% \end{syntax}
%
% We Austrians, for example, prefer to write `\"oS' instead of `ATS'.
% We don't have to write |\EUROSYM{ATS}{\"oS}| though, because this national
% style (like those of some other countries) is already predefined. If your
% national style is still missing, please drop me a line, and I will insert it.
% Meanwhile the \textsc{ISO} currency codes are used in such cases.
%
% \begin{example}
% |\EURO{FRF}{16.3}|&      \EURO{FRF}{16.3}\\
% |\EUROSYM{FRF}{Francs}|&\\
% |\EURO{FRF}{16.3}|&      \EUROSYM{FRF}{Francs}\EURO{FRF}{16.3}
% \end{example}
%
% The official Euro symbol is not provided by default, since there are a lot of
% different fonts and methods to produce an \euro\ sign. Type
% |\EUROSYM{EUR}{|\(\langle\)\textit{euro symbol}\(\rangle\)|}| to
% replace the word `Euro' with your local \euro\ sign.
% (I'm still hoping that some day the text companion fonts will contain the official in
% addition or instead of the phantasy \emph{Euro} symbols.)
% This documentation, for example, says |\EUROSYM{EUR}{\euro}|
% because it has its own |\euro| symbol built-in. (Isn't it beautiful?)
%
% \begin{example}
% |\EURO{LUF}{137.8}|&      \EURO{LUF}{137.8}\\
% |\EUROSYM{EUR}{\euro}|&\\
% |\EURO{LUF}{137.8}|&      \EUROSYM{EUR}{\euro}\EURO{LUF}{137.8}
% \end{example}
%
% \EUROSYM{EUR}{\euro}    ^^A define this globally now
%
%
% Writing e.\,g.~|\EURO{ATS}{...}| again and again is cumbersome, so it's recommended to
% define macros for the most often used currency units. You may put such definitions
% into your local configuration file (see section~\ref{sec:config}).
%
% \begin{example}
% |\newcommand*\ATS{\EURO{ATS}}|\\
% |\ATS{9.90}|& \ATS{9.90}\\
% |\ATS[ITL]{19.90}|& \ATS[ITL]{19.90}
% \end{example}
% \null
%
%
%
%
% \subsection{The package options}
% \label{sec:options}
%
% The |euro| package provides six package options. See table~\ref{tab:options} for
% a short demonstration.
%
% \begin{labeling}{\opt{emdash}~~}
% \item[\textbf{\opt{eco}}]
%   The \opt{eco} option typesets monetary amounts as, I think,
%   economists prefer it, with \textsc{ISO} codes preceding the values.
% \item[\textbf{\opt{dots}}]
%   The \opt{dots} option inserts dots as three-digits group
%   separators. (Default is a little space like \rule{.4pt}{.75em}\,\rule{.4pt}{.75em}.)
% \item[\textbf{\opt{table}}]
%   Turns the \emph{table mode} globally on.
%   While integers are normally printed without decimal point and fractional part (sic!),
%   it may especially in tables be desirable to typeset a decimal point followed by a dash.
%   See section \ref{sec:align} for how to keep this behavior local to a particular table.
% \item[\textbf{\opt{emdash}}]
%   Lets the \opt{table} dashes be `---'. Doesn't turn on \emph{table mode}.
%   (This option is selected by default, so it doesn't make much sense at
%   the moment. But this might change some day.)
% \item[\textbf{\opt{endash}}]
%   Lets the \opt{table} dashes be `--'. Doesn't turn on \emph{table mode}.
% \item[\textbf{\opt{zeros}}]
%   Lets zeros be printed instead of dashes. Doesn't turn on \emph{table mode}.
% \end{labeling}
%
%
% \begin{table}
% \begin{center}
%^^A the options are only faked here   ;-)
% \makeatletter
% \begin{tabular}{lr}%

% \end{center}
% \caption{Package options}
% \label{tab:options}
% \end{table}
%
%
%
%
% \subsection{Adding currency units}
%
% If some day further countries will join the \emph{Euro-zone,} you can easily
% add their currency units to your document files or, better, to
% your local `|euro.cfg|' configuration file.
% The |euro| package will then, of course, be updated as soon as possible.
%
% \begin{syntax}
% |\EUROADD{|\<ISO code>|}{|\<national style/symbol>|}{|\<conversion rate>|}|
% \end{syntax}
%
% The conversion rate describes, how many units of the new currency
% equal 1~\euro. You can also add currencies, that will
% probably never become member of the \emph{Euro-zone,} like the US-\$. But be aware that such
% conversion rates may change daily/hourly! See \(\langle\)|http://europa.eu.int/|\(\rangle\) for the
% actual rates. The used \textsc{ISO} code serves as identifier for the
% respective currency unit.
%
% \EUROADD{GBP}{\textit{\char`\$}}{0.6694}
% \begin{example}
% |%  1 Euro = 0.6694 Pound Sterling    (March 11, 1999)|\hspace*{-4.5cm}\\
% |%|\\
% |\EUROADD{GBP}{\textsterling}{0.6694}|\hspace*{-3cm}\\
% |\newcommand*\GBP{\EURO{GBP}}|\\
% \\
% |\GBP{47.11}|&            \EURO{GBP}{47.11}\\
% |\GBP[FRF]{47.11}|&       \EURO{GBP}[FRF]{47.11}\\
% |\EURO{EUR}[GBP]{1}|&     \EURO{EUR}[GBP]{1}
% \end{example}
%
% The pound symbol in this example looks a bit too slanted. You'd better take
% |\textsterling| from the |textcomp| package, which I didn't.
%
%
%
%
%
%
% \section{Further customization}
% \label{sec:format}
%
% The desirable format for monetary amounts may differ from country to country and from purpose to purpose.
% The |euro| package uses three kinds of format strings to customize the format, each of which may
% consist of some \emph{reserved keywords} and any other \TeX\ commands. It's a good idea
% to put such commands in your local configuration file (see section~\ref{sec:config}).
%
%
%
% \subsection{The main format}
%
% The main format defines how source and destination currency shall be arranged.
%
% \begin{syntax}
% |\EUROFORMAT{main}{|\<main format string>|}|
% \end{syntax}
%
% The \emph{reserved keywords} |\in| and |\out| stand for the source and the destination currency.
% The following table shows some possible formats with the first line showing the
% default definition.
%
% \begin{example}[.58\hsize]
%                                         & |\EURO{ATS}{30}| yields\\[.5ex]
% \hline\\[-1.5ex]
% |\EUROFORMAT{main}{\in\ (\out)}|&         \EURO{ATS}{30}\\
% |\EUROFORMAT{main}{\in\slash\out}|&       \EUROFORMAT{main}{\in\slash\out}\EURO{ATS}{30}\\
% |\EUROFORMAT{main}{\in\ ($=$\,\out)}|&    \EUROFORMAT{main}{\in\ ($=$\,\out)}\EURO{ATS}{30}\\
% |\EUROFORMAT{main}{\in\ (that is \out)}|& \EUROFORMAT{main}{\in\ (that is \out)}\EURO{ATS}{30}\\
% |\EUROFORMAT{main}{\out}|&                \EUROFORMAT{main}{\out}\EURO{ATS}{30}
% \end{example}
% \null
%
%
%
%
% \subsection{The currency format}
%
%
% The currency format defines how the source and the destination currency
% shall be formatted.
%
% \begin{syntax}
% |\EUROFORMAT{in}{|\<currency format string>|}|\\
% |\EUROFORMAT{out}{|\<currency format string>|}|
% \end{syntax}
%
% The \emph{reserved keywords} |\val|, |\iso| and |\sym| have a special meaning, but
% almost every other \TeX\ command may be used as well.
%
% \medskip\indent
% \begin{tabular}{@{\texttt\bgroup}l@{\egroup\quad}p{.8\hsize}}
% \string\val&   monetary amount\\
% \string\iso&   \textsc{ISO} currency code\\
% \string\sym&   national currency style\slash tag (if defined; \textsc{ISO} code else)\\
% \end{tabular}
%
% \medskip\noindent
% For some currency units
% the |\sym| command produces only the \textsc{ISO} code instead of the national style,
% which I didn't know. This will (with your help!) be changed in future releases.
% The following table shows the most obvious arrangements. All said about the |in| format
% string is also true for the |out| format.
%
% {\EUROFORMAT{main}{\in}\newcommand\EUROaux{\hspace{1.2cm}}
% \begin{example}[.58\textwidth]

% \subsection{The number format}
%
% The number format, finally, defines how the numbers themselves should be
% typeset considering positive\slash negative numbers, rounding and so on.
%
% \begin{syntax}
% |\EUROFORMAT{all}{|\<number format>|}|\\
% |\EUROFORMAT{|\<ISO currency code>|}{|\<number format>|}|
% \end{syntax}
%
% The definitions labeled with |all| will be used for all currency units.
% By using |\EUROFORMAT| with one of the three-digits \textsc{ISO} codes
% as the first argument, these general settings can be overridden for this
% currency.
% Only the \emph{Italian Lira} is defined this way by default, because it
% wouldn't make sense to write \emph{Lira} amounts with two fractional digits
% like the other European currencies.^^A
% \footnote{The package, for example, says something like
% \texttt{\string\EUROFORMAT\char`\{ITL\char`\}\char`\{\string\round\char`\{0\char`\}\char`\}}.} ^^A   8-P
%
% The \textit{number format string} may contain the commands |\form|,
% |\round|, |\zero|, |\plus|, and |\minus|, each of which takes one or
% more arguments. You have only to mention the points that shall differ
% from the default behavior.
% Such a number format might look horrible like this
%
% \begin{example}
% |\EUROFORMAT{all}{%|\\
% |  \form{\,}{,}{\,}%|\\
% |  \round{-2}%|\\
% |  \zero{0}{0}{}%|\\
% |  \plus{}{}%|\\
% |  \minus{\(-\)}{}}|
% \end{example}
%
% which, by fortune, is the predefined default format\footnote{Well, that is a lie: In fact,
% it is only the equivalent of the default definition, which is defined in another way.},
% but it might as well be empty or contain only one of the commands and its arguments.
% Here again all arguments are predefined quite reasonably, so you won't have
% to bother with these verbose definitions.
%
% To make further explanations easier, figure~\ref{fig:nomencl} describes the elements
% that a number may consist of (using my own nomenclature).

% \subsection{Tables and alignment}
% \label{sec:align}
%
% To achieve proper alignment in tables there's an |\align| command that
% can be used in any of the different format strings no matter if it's a
% \emph{main}, an \emph{in}, \emph{out}, or one of the \emph{number} formats.
% This command is to be stated before the
% concerned |\in|, |\out|, or |\val| command, respectively.
% It lets a number's fractional part have
% no width, thus allowing to align such numbers properly in a flush-right
% table column (|r| column). The example below also shows how to use
% the \DescribeMacro{\table}|\table| keyword. It turns the \opt{table}
% mode on for the current table. To turn it on for the whole document,
% use the \opt{table} package option. If you find the `---' dashes
% too long, you can load the package with the \DescribeOption{endash}\opt{endash}
% option.

%
%
% \subsection{Dirty tricks}
%
%
% Of course, the format doesn't have to deal with the \euro, nor with monetary amounts
% at all. (The |EUR| currency in the following examples has no meaning,
% we could also have used any other currency, provided that no |\out| command
% is used within the \emph{format string.})
%
% \begin{example}[.6\textwidth]
% |\newcommand*\USD[1]{{%|\\
% |  \EUROFORMAT{main}{\in}%|\\
% |  \EUROFORMAT{in}{\val\,\$}%|\\
% |  \EUROFORMAT{EUR}{\form{,}{.}{,}\round{-2}}%|\hspace*{-1cm}\\
% |  \EURO{EUR}{#1}}}|\\[1.5ex]
% |\USD{-123450.6789}|& \USD{-123450.6789}\\[1ex]
% \end{example}
%
% These examples are probably too complicated for the simple things they do.
% But they may serve as examples of how to use some of the customization
% commands.
%
% \begin{example}[.6\textwidth]
% |\newcommand*\NUM[1]{{%|\\
% |  \EUROFORMAT{main}{\in}%|\\
% |  \EUROFORMAT{in}{\val}%|\\
% |  \EUROFORMAT{EUR}{\form{,}{.}{,}\round{-10}}%|\hspace*{-1cm}\\
% |  \EURO{EUR}{#1}}}|\\[1.5ex]
% |\NUM{1000} red ants|& \NUM{1000} red ants
% \end{example}
% \null
%
%
%
% \subsection{The default settings}
%
% The following lines show how the |\EURO| command's default behavior
% could have been defined. The real settings, however, were defined on
% a lower programming level.
%
% \begin{example}[.6\textwidth]
% |\EUROFORMAT{main}{\in\ (\out)}|\\
% |\EUROFORMAT{in}{\val~\sym}|\\
% |\EUROFORMAT{out}{\val~\sym}|\\
% |\EUROFORMAT{all}{%|\\
% |  \form{\,}{,}{\,}%|\\
% |  \round{-2}%|\\
% |  \zero{0}{0}{}%|\\
% |  \plus{}{}%|\\
% |  \minus{\(-\)}{}}|\\
% |\EUROFORMAT{ITL}{%|\\
% |  \round{0}}|
% \end{example}
% \null
%
%
%
% \subsection{The configuration file}
% \label{sec:config}
%
% If you want to change the predefined settings, create a
% file named `|euro.cfg|' and put it in a directory, where \TeX\
% can find it. This configuration file will then be loaded
% at the end of the |euro.sty| file, so you may redefine
% any settings or commands, select package options and even
% introduce new package options. But if you intend to give
% your documents to others, don't forget to give them the
% required configuration files, too! That's how such a file
%  could look like:
%
% \begin{example}[.92\textwidth]
% |% introduce the US-Dollar and the British Pound Sterling|\\
% |\EUROADD{USD}{\$}{1.0891}|\\
% |\EUROADD{GBP}{\textsterling}{0.6694}|
% \end{example}
%
% \indent
% \begin{example}[.85\textwidth]
% |% let Italian Lire be rounded to 10s|\\
% |\EUROFORMAT{ITL}{\round{1}}|\\
% |% and let their symbol be only `L.'|\\
% |\EUROSYM{ITL}{L.}|
% \end{example}
%
% \indent
% \begin{example}[.92\textwidth]
% |% declare a new package option `bold',|\\
% |% which typesets the source currency in boldface type|\\
% |\DeclareOption{bold}{%|\\
% |  \EUROFORMAT{main}{\textbf{\in} (\out)}}|
% \end{example}
%
% \indent
% \begin{example}[.85\textwidth]
% |% always select the `endash' option|\\
% |\ExecuteOptions{endash}|\\
% |\endinput|

% \section*{The European Union \&\ Patents on Software}
%
%^^A^^  NOTE TO DISTRIBUTORS: If you feel like distributing the euro package documentation with
%^^A^^  this section removed or modified, note the special copyright clause that applies in this case!
%
% Because this package is dedicated to the European Union's official currency,
% I feel the obligation --~in the name of freedom and democracy, and as a citizen
% of the EU~-- to comment on today's decision on the ``Computer Implemented
% Inventions Directive'':
%
% Today, 2005/03/07, unelected bureaucrats --~the European Council of ministers~-- decided
% to ignore the objections and clear will of the elected European Parliament, those of the
% Committee on Legal Affairs~(JURI), the presidency of the European Parliament, of several
% national parliaments, and nothing less than the interests of the citizens of the European Union.
% Instead, they chose to fulfill the wishes of software industry giants (some of which have
% been convicted of abusing their monopoly power in several countries), and the wishes of
% bureaucrats from the European Patent Office, which has illegally granted 30.000~software
% patents already.
%
% This is an incredible offense and disgusting abuse of power. It has yet to be
% investigated, which r\^ole corruption played in this plot, for which there
% seem to be strong signs. We are facing nothing less than an oligarchy of
% unelected bureaucrats who feel more obliged to maintaining the wealth of the richest
% man on earth, than the interests of the European citizens and the European
% economy. There is still hope that the European Parliament will reject the
% directive in the second reading. This appeal will remain in the documentation, though,
% as long as the European Parliament is treated as a fig leaf for undemocratic decisions.
% And should this directive become effective, and should I ever encounter conflicts
% with software patent claims in \emph{any} of my software packages, the |euro|~package
% will be the first that I will withdraw.
%
% This is a sad day. Shame on the European~Council! Shame on the European~Commission!
