You can truncate the decimal part. Here, I keep only the first digit.
N.B. You must verify that such change in an internal macro used everywhere
has no bad side effect somewhere. I test it only on this example...

Remi.Coulom> Another question I have: is there a pstricks option that allows to select the
Remi.Coulom> type of line join (setlinejoin, in Postscript). I would like to use bevel join,

There is not such option accessible by a PSTricks macro or parameter.
You must set it directly in PostScript, as here:
\documentclass[a4paper]{article}
\usepackage{pstricks}
\pagestyle{empty}
\begin{document}
\psset{subgriddiv=0,griddots=5,linewidth=0.3}
\begin{pspicture}(2,2)\psgrid
\psline(0,0)(1,2)(2,0)
\end{pspicture}
\hfill
\begin{pspicture}(2,2)\psgrid
\pscustom{%
\code{1 setlinejoin}
\psline(0,0)(1,2)(2,0)}
\end{pspicture}
\hfill
\begin{pspicture}(2,2)\psgrid
\pscustom{%
\code{2 setlinejoin}
\psline(0,0)(1,2)(2,0)}
\end{pspicture}
\end{document}
