Internally the value is used in PS mode. The reason why you
can use any PS code _without_ the preceeding !:

\documentclass{article}
\usepackage{pst-plot}
\begin{document}
\psset{yunit=2,xunit=10}
\begin{pspicture}(-0.1,-0.5)(1,2)
\psaxes{->}(0,0)(-0.05,-0.5)(0.75,1.75)
\psyTick(1.57){\frac{\pi}{2}}
\psyTick(PI 2 div){\frac{\pi}{2}}
\psxTick(0.08943089){\frac{110}{1230}}
\psxTick(220 1230 div){\frac{220}{1230}}
\end{pspicture}
\end{document}
