  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,
    Remi.Coulom> but pstricks seems to be using miter join. I did not manage to find this option

  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}
