For example, a format which was 80-bit Intel expanded to 128 bits by adding 48 bits required to be all zeroes would be a legitimate implementation of extended, and in any case extended precision is not required! -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
