The only thing supported by ramp is the `Rational` type, which has arbitrary precision. This library isn't really under active development, so that's pretty much all I can offer right...

Hey, sorry for the delay on this. The original author of this crate isn't really around to do more dev work, and I don't think I have the expertise to...

This is doable. Do you have a motivating use case for a feature like this?

Hmm I see. For the sake of brevity, I would hold off on implementing this inside ramp, since it can be done pretty easily with an `Int::to_str_radix` followed by a...

a low-level extended gcd function like `ll::gcd` would be much appreciated, if you'd like to contribute one. Otherwise, I may do that in the future.

That's a GCD implementation. The extended GCD `egcd(x,y)` returns integers `(a,b,g)` such that `g = gcd(x,y)` and `x*a + y*b = g`. It shouldn't be too hard to copy most...

Thank you for the contribution! These are a lot of changes. Could you explain the reasoning behind them? 1. What is the use case for these functions? When would you...
