reassign 55268 pdl thanks The GNU C Library does not install a <nan.h> on any architecture, the closest is <bits/nan.h>, which is for use only by other glibc headers. The correct way to get the `NAN' constant is by including <math.h>, according to the GNU C Library manual. << - Macro: float NAN An expression representing a value which is "not a number". This macro is a GNU extension, available only on machines that support the "not a number" value--that is to say, on all machines that support IEEE floating point.
You can use `#ifdef NAN' to test whether the machine supports NaN. (Of course, you must arrange for GNU extensions to be visible, such as by defining `_GNU_SOURCE', and then you must include `math.h'.) >> -- Joel Klecker (aka Espy) <URL:mailto:[EMAIL PROTECTED]> Debian Package Maintainer for the GNU C Library.
