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.
