[erlang-questions] Rational arithmetic library?

Anyone have a good rational number arithmetic library? I can't be the first
to need one, surely...
The background is that I need to do some EXACT arithmetic on non-integer
numbers, so floating point won't do. Of course, rational arithmetic is easy
to implement--and I've done so--but I realise there are choices over where
exactly to take gcds, that may have a big impact on performance once the
numbers involved start getting large. It would be nice just to use a library
that has already been tuned, rather than need to tune my own.
I will say this for mine though: it's very thoroughly tested! If you're
interested, it's at
