Struct sp_arithmetic::rational::RationalInfinite

source · [−]

pub struct RationalInfinite(_, _);

Expand description

A wrapper for any rational number with infinitely large numerator and denominator.

This type exists to facilitate cmp operation on values like a/b < c/d where a, b, c, d are all BigUint.
