The default with gcc on x86 is to use 80-bit extended precision registers, compared with 64-bit on the other architecture. It gives a differently rounded result in this case, since the underlying binary representation is on the borderline between -79.937384... and -79.9373839999... Use the rint type functions to round to the nearest integer reliably. -- Brian Gough Network Theory Ltd, Publishing "An Introduction to GCC" --- http://www.network-theory.co.uk/
