A question for the net.tex.experts:

I need to generate (in a \special) only the NUMERIC part of
a TeX dimension.  For example, if \the\pagewidth gives 350.642pt,
I would like something like \thenumber\pagewidth to give 350.642

Along the way, I have been able to strip off just the INTEGER part,
with the following macros:

\def\integerpart#1.#2\end{#1}
\newcommand{\theinteger}[1]{\expandafter\integerpart\the#1\end}
\typeout{integer part of \the\pagewidth\space = \theinteger\pagewidth}

Any suggestions?

Thanks in advance,
