Struct sp_arithmetic::rational::RationalInfinite

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.

Implementations

impl RationalInfinite

pub fn n(&self) -> &BigUint[−]

Return the numerator reference.

pub fn d(&self) -> &BigUint[−]

Return the denominator reference.

pub fn from(n: BigUint, d: BigUint) -> Self[−]

Build from a raw n/d.

pub fn zero() -> Self[−]

Zero.

pub fn one() -> Self[−]

One.
