I've seen no mention in this thread of IEEE Std 754-2008 which was published last month. minNum(x, y) and maxNum(x, y) return a floating-point number if the other argument is NaN.
The OP's question is about the sign of NaN. In 754r it can be tested, copied, etc. Operations involving NaNs propagate the payload but not the sign bit AFAIK. -- Pete Forman -./\.- Disclaimer: This post is originated WesternGeco -./\.- by myself and does not represent [EMAIL PROTECTED] -./\.- the opinion of Schlumberger or http://petef.22web.net -./\.- WesternGeco. _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
