I'm having trouble imagining a real use case for either of these methods. When I'm using Rational, it's almost certainly because I want exact arithmetic; if I'm getting results with huge denominators and numerators then either that's what I really want, or I probably shouldn't have been using Rational in the first place... The only semi-use case I see is providing some way for users to turn the float 1.1 into the rational 11/10, instead of Rational(2476979795053773L,2251799813685248L). So I'd say leave both these methods out for now---it would be easy enough to add them later if it turns out there's a real need. Just my 200/391 UK pennies :) Mark
