Computers should have a more accurate representation of real numbers Interesting idea  and well worth raising. Perhaps related (but also a little different) is Interval Arithmetic. Just set your precision, do your calculations, and you end up with an upper and lower bound (for the given precision/inputs)  within which the exact value lies. I've played with a C library, and a perl extension (that I wrote) that wraps that C library .... but only *played*. Cheers, Rob
