Double-Precision Values: Bit-by-Bit Sensitivity

Although both architectures are IEEE 754 compliant, there are differences in the rounding procedure used by each when operating on double-precision numbers. If your application is sensitive to bit-by-bit values in double-precision numbers, be aware that the same computation performed on each architecture may produce a different numerical result.
