Have you tried ABC language from the Netherlands?
It features exact arithmetic even beyound the decimals that are shown. For
example:
1 / 3 = 0.3333333333333333333333333333333...
When you multiply it back by 3, you get 1. It seems that it never loses
precision. I do not know how they do that: perhaps maintaining the numbers
as rational fractions.
Regards.
