Floating point problems

[Heinz Ulrich Stille <Heinz Ulrich Stille mbi-os de>]

Hi!

What's wrong with the following program?

main() {
	double x = 1.0;
	x *= 1e-310;
}

This results in a floating point exception on my Ruffian (for values
somwhere between 1e-300 and 1e-325, independent of kernel and compiler),
but not on any intel. The assembler output seems to indicate that the
two values are just loaded into registers and multiplied.
What is going on?

MfG, Ulrich
