Hi Yuan,
I'm not 100% sure, but my guess would be that one or both programs were not
compiled with strict IEEE 754 compliance enabled.
Without strict compliance, the compiler is at liberty to take advantage of
optimizations which may result in twitchy differences in least significant
digits of floating point numbers.
