Now, this is an argument Smile

Applied. (I have deleted float version altogether - either it is MSC on Win32 which is unable to do it right using int64, or it is GCC or MSC on ARM and ARM does not have FP).

Well, even if usually MSC optimizes better than GCC, that's not always true Smile

BTW, I'm surprised on how bad does it MSC, having hardware instruction on x86 processors for 32x32->64 bit multiply (signed AND unsigned) and 64/32->32 bit divide. Maybe they're still anchored to good old 8088 assembly code... Smile
