One problem is: can your C compiler handle it? Now, on those platforms without 64 bit support, a double float has a lot more mantissa bits than 32, typically 50-something (on a total of 64 bits). This means that all integers with up to more than 50 significant bits can exactly be represented. That would be a lot better than the current situation of 32 bits. -- Bart.
