[pstricks] problem with random number generation?

[Goebel, Juergen, OPE26]

Hi,

Please have a look at the following sample. The result
isn't exactly what I've expected. There should be
something wrong, but I can't see what it is. Your help
would be appreciated.

Regards,

Jürgen


% two-dimensional uniform distribution
\documentclass{scrartcl}
\usepackage{pst-all}
\begin{document}
\pstVerb{%
   rrand srand                 % initializes the random generator
   /k 20 def
}%
\psset{unit=1mm}
\begin{pspicture}(-20,-20)(20,20)
  \psframe(-20,-20)(20,20)
  \psplot[plotpoints=1000,showpoints=true,
          dotsize=1pt,linestyle=none]{0}{0}{%
     rand 2147483647 div 0.5 sub 2 mul
     k mul
     exch
     rand 2147483647 div 0.5 sub 2 mul
     k mul
  }

\end{pspicture}
\end{document}
