Hi!

Some recent ports that I did, crashed with "Floating Point Exceptions"
in totally inconspicious looking routines (aren't they all? :-). This made
me mistrust the FP math lib on our machines.

Now I want to test them, and for this I'm looking for a program that
does exactly that - test 'em. Pass funny values to tri-gon. routines and
such, just generally pushes them to the edge and tells me when the
routine can't handle the arguments.

oh, BTW, I'd also welcome hints on work-arounds for infamous FP bugs,
as long as they don't require a new math-lib. Ours uses the FPU and
understandably I wouldn't like to give up that speed.

Thanks in advance.
Mike
