Struct sp_runtime::Rational128

Convert self to a similar rational number where denominator is the given den. This only returns if the result is accurate. Err is returned if the result cannot be accurately calculated.

source

pub fn lcm(&self, other: &Rational128) -> Result<u128, &'static str>

Get the least common divisor of self and other.

This only returns if the result is accurate. Err is returned if the result cannot be accurately calculated.

source

pub fn lazy_saturating_add(self, other: Rational128) -> Rational128

A saturating add that assumes self and other have the same denominator.

source

pub fn lazy_saturating_sub(self, other: Rational128) -> Rational128

source

pub fn checked_add(
self,
other: Rational128
) -> Result<Rational128, &'static str>

Addition. Simply tries to unify the denominators and add the numerators.

Overflow might happen during any of the steps. Error is returned in such cases.

source

pub fn checked_sub(
self,
other: Rational128
) -> Result<Rational128, &'static str>

Subtraction. Simply tries to unify the denominators and subtract the numerators.

Overflow might happen during any of the steps. None is returned in such cases.
