Tim Peters added the comment: The functionality of what was called (and I agree confusingly so) "sign()" here is supplied by "signbit()" in C99. That standard isn't free, but the relevant part is incorporated in the free Open Group standards:
http://www.opengroup.org/onlinepubs/000095399/functions/signbit.html The 754 standard says NaNs have sign bits, but assigns no meaning to them. In particular, the value of the sign bit of a NaN resulting from a string->double routine applied to the string "nan" isn't defined by 754, or (AFAICT) by C99 either. ---------- nosy: +tim_one __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1640> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
