It's difficult to say as the existing code makes *no sense*. Those are integer constants which are supposed to be used in struct exception, which is then passed to the matherr() function. In the glibc case they happen to have a value of 3 for OVERFLOW and 4 for UNDERFLOW, but that might differ on other systems. In any case they are not supposed to be used in a comparison with floating point values. -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
