The regression tests don't need to be exhaustive, you could just pick a
few values throughout the range of each function you test, and make a
regression test like:
x = 3/2;
if (x != 1.5)
printf("FP regression!\n");
Heck, you could throw all the calculations into one file.
I couldn't understand much of the rest of your e-mail, and I doubt that
anyone else could either. That's why you're the best person to write any
type of regression test for this.
