\label{labdefault}
\noindent Name: \textbf{default}\\
\phantom{aaa}default value for some commands.\\[0.2cm]
\noindent Library names:\\
\verb| sollya_obj_t sollya_lib_default()|\\
\verb| int sollya_lib_is_default(sollya_obj_t)|\\[0.2cm]
\noindent Description: \begin{itemize}
\item \textbf{default} is a special value and is replaced by something depending on the
context where it is used. It can often be used as a joker, when you want to
specify one of the optional parameters of a command and not the others: set
the value of uninteresting parameters to \textbf{default}.
\item Global variables can be reset by affecting them the special value \textbf{default}.
\end{itemize}
\noindent Example 1:
\begin{center}\begin{minipage}{15cm}\begin{Verbatim}[frame=single]
> p = remez(exp(x),5,[0;1],default,1e-5);
> q = remez(exp(x),5,[0;1],1,1e-5);
> p==q;
true
\end{Verbatim}
\end{minipage}\end{center}
\noindent Example 2:
\begin{center}\begin{minipage}{15cm}\begin{Verbatim}[frame=single]
> prec;
165
> prec=200;
The precision has been set to 200 bits.
\end{Verbatim}
\end{minipage}\end{center}
