\subsection{absolute}
\label{lababsolute}
\noindent Name: \textbf{absolute}\\
\phantom{aaa}indicates an absolute error for \textbf{externalplot}, \textbf{fpminimax} or \textbf{supnorm}\\[0.2cm]
\noindent Library names:\\
\verb| sollya_obj_t sollya_lib_absolute()|\\
\verb| int sollya_lib_is_absolute(sollya_obj_t)|\\[0.2cm]
\noindent Usage:
\begin{center}
\textbf{absolute} : \textsf{absolute$|$relative}\\
\end{center}
\noindent Description: \begin{itemize}
\item The use of \textbf{absolute} in the command \textbf{externalplot} indicates that during
plotting in \textbf{externalplot} an absolute error is to be considered.
See \textbf{externalplot} for details.
\item Used with \textbf{fpminimax}, \textbf{absolute} indicates that \textbf{fpminimax} must try to minimize
the absolute error.
See \textbf{fpminimax} for details.
\item When given in argument to \textbf{supnorm}, \textbf{absolute} indicates that an absolute error
is to be considered for supremum norm computation.
See \textbf{supnorm} for details.
\end{itemize}
\noindent Example 1:
\begin{center}\begin{minipage}{15cm}\begin{Verbatim}[frame=single]
> bashexecute("gcc -fPIC -c externalplotexample.c");
> bashexecute("gcc -shared -o externalplotexample externalplotexample.o -lgmp -l
mpfr");
> externalplot("./externalplotexample",absolute,exp(x),[-1/2;1/2],12,perturb);
\end{Verbatim}
\end{minipage}\end{center}
