Specifically, is the result of (**): float -> float -> float guaranteed to be the same for the same input regardless of the compiler's version? Are any number of digits guaranteed to be correct? In which case I could truncate. I do not care too much about exactitude, but I need the operation's semantic to be exactly defined.
