3644 # precision than what's specified in the source and doing so
3645 # is more efficient than constantly rounding up to 64-bit or
3646 # 32-bit precision as specified in the source, the compiler,
3647 # especially in the optimized mode, tries very hard to keep
3648 # values in x87 floating-point stack (in 80-bit precision)
3649 # as long as possible. This has important side effects, that
3650 # the real value used in computation may change depending on
3651 # how the compiler did the optimization - that is, the value
3652 # kept in 80-bit is different than the value rounded down to
3653 # 64-bit or 32-bit. There are possible compiler options to
3654 # make this behavior consistent (e.g. -ffloat-store would keep
3655 # all floating-values in the memory, thus force them to be
3656 # rounded to its original precision) but they have significant
3657 # runtime performance penalty.
