\subsection{points}
\label{labpoints}
\noindent Name: \textbf{points}\\
\phantom{aaa}controls the number of points chosen by \sollya in certain commands.\\[0.2cm]
\noindent Library names:\\
\verb|   void sollya_lib_set_points_and_print(sollya_obj_t)|\\
\verb|   void sollya_lib_set_points(sollya_obj_t)|\\
\verb|   sollya_obj_t sollya_lib_get_points()|\\[0.2cm]
\noindent Usage: 
\begin{center}
\textbf{points} = \emph{n} : \textsf{integer} $\rightarrow$ \textsf{void}\\
\textbf{points} = \emph{n} ! : \textsf{integer} $\rightarrow$ \textsf{void}\\
\textbf{points} : \textsf{constant}\\
\end{center}
Parameters: 
\begin{itemize}
\item \emph{n} represents the number of points
\end{itemize}
\noindent Description: \begin{itemize}

\item \textbf{points} is a global variable. Its value represents the number of points
   used in numerical algorithms of \sollya (namely \textbf{dirtyinfnorm},
   \textbf{dirtyintegral}, \textbf{dirtyfindzeros}, \textbf{plot}).
\end{itemize}
\noindent Example 1: 
\begin{center}\begin{minipage}{15cm}\begin{Verbatim}[frame=single]
> f=x^2*sin(1/x);
> points=10;
The number of points has been set to 10.
> dirtyfindzeros(f, [0;1]);

> points=100;
The number of points has been set to 100.
> dirtyfindzeros(f, [0;1]);
