\section{Introduction}

The upcoming \LaTeX3 can already be used. It is more or less stable and
macros will change only if really needed.


\section{Package options}
The package knows two optional arguments which, of course, have a corresponding
name in package \texttt{siunitx}. One can also use that one.

\begin{tabularx}{\linewidth}{@{}llX@{}}\toprule
\emph{name} & \emph{\texttt{siunitx}} & \emph{description}\\\midrule
\texttt{useComma} & \texttt{output-decimal-marker=\{,\}} & Output always a comma instead of the default dot.\\
\texttt{roundDigit}& \texttt{round-mode=places,round-precision=<value>} & round the given digit number.\\
\bottomrule
\end{tabularx}

\section{Using the macros}

\begin{LTXexample}[pos=t]
\psCalculate{3.14126*314^2}\\  % Uses \num from siunitx
\pscalculate{3.14126*314^2}    % doesn't use \num
\end{LTXexample}

Without using any additional argument all available digits are printed.

\section{Optional arguments}

All optional arguments of package \texttt{siunitx} can be used:

\begin{LTXexample}[pos=t]
\psCalculate[group-digits=false]{3.14126*314^2}\\ 
\psCalculate[output-decimal-marker={,}]{3.14126*314^2/sin(3)}\\
\psCalculate[exponent-product=\cdot,scientific-notation=true]{3.14126*314^2/sin(3)}\\
\psCalculate[scientific-notation=engineering]{3.14126*314^2/sin(3)}\\
\psCalculate[fixed-exponent=2,scientific-notation=fixed]{3.14126*314^2/sin(3)}\\
\psCalculate[round-precision=3]{3.14126*314^2/sin(3)}\\
\psCalculate[round-mode=places,round-precision=3]{3.14126*314^2/sin(3)}
\end{LTXexample}

For more optional argument to format the output have a look at the documentation of \texttt{siunitx}.
