It's an IEEE-754 problem... Only the above operations and sqrt require full accuracy. Just about every other floating point operation is allowed to be less accurate and fully compliant, and widely differ in exact answers. Even on say x86, using SSE vs FPU vs libc (which often will not use above versions in order to be more accurate) will give different answers.
