Thanks to Gabriel we may have an is_nan() right now.
Is there anything else that the interval library uses which might be better

All the hardware rounding mode selection stuff. It's equivalent to the

So where does that leave us? There must be some reason Gennadiy's code is
producing results one or two epsilons greater than expected.
It's just because the testcases are wrong. For example, line 157, there
is:

Could you be more specific. On which machines for instance ?
Me, myself personally tested on Intel Celeron 733, OS WinXP.
Compiler used: gcc 3.2 mingw port for windows.

I found a bug in the interval library. but when I corrected it, I stumbled
over another problem: this bug was ironically what allowed the library to
