Thank you.
That doesn't run on an error, but scales way too much.
With
\def\LPscale{0.6315789}
the command should have the same effect as
\def\LPkscale{632}

But
\edef\LPkscale{\the\numexpr1000\LPscale\relax}
seems to scale about 100 times too much.

I simply(?!?) want to multiply some floating point value with 1000 to  
set the "scale" parameter of \externalfigure.
Why ist this so difficult?

Is there a book or tutorial on TeX as a programming language somewhere?
