Next version of Math::BigInt (v1.21) will contain my experimental module
from last year, called Math::BigFraction which implements exactly this.
But as Andy said, we need still precision and rounding. Perhaps even on a
per-variable basis.

PS: Is it not custom to CC: the people on this list in case they do not
