Actually Uwe, that last one is different from what Bob and I get:
[EMAIL PROTECTED] ~ $ ./test
Please enter the num: 1e-320
Please enter the den: 2
9.99989e-321/2 = 4.99994e-321
Now I'm confused. Which is supposed to be correct?
My result is the same as in the initial mail from Tyson. This is what he says:
0/0 = 0 (should be nan)
1/0 = 0 (should be inf)
1e-320/2 = 0 (should be 5e-321: 1e-320 is a denormalized)
So it seems that the last test works correct on your machine. The
difference is:
a) newer kernel on my machine - but I think nothing changed between
.16 and .15, could somebody make a diff in fixup code?
b) gcc 4.0 vs gcc 3.3
