hi list,

in the following minimal example, I want to compute the arctan of  
0.75, which is approximately 37 degrees; but it doesn't work:


\documentclass[12pt]{article}
\usepackage[margin=1cm]{geometry}
\usepackage{pst-3dplot,pst-plot,pst-grad}
\usepackage{pstricks-add}

\begin{document}

\begin{pspicture*}(-3,-3)(12,15)
\psset{unit=.1cm,coorType=2}
%\pstThreeDDot[SphericalCoor](20,180,36.8698976)%works!
\pstThreeDDot[SphericalCoor](20,180,0.75 atan)%does not work
\end{pspicture*}

\end{document}


???
