<<Obviously, it is useless to talk about the ill effects of rearranging
floating point expressions without having a solid reference. To simplify the
analysis below, this project confines itself to the targets that support the
IEEE-754 Standard, using the standard rounding mode for reference.
Once again, the IEEE-754 standard has nothing whatsoever to say about
evaluation of floating-point expressions in high level languages.
