Trait malachite_base::num::arithmetic::traits::ModPowerOf2SubAssign

pub trait ModPowerOf2SubAssign<RHS = Self> {
    // Required method
    fn mod_power_of_2_sub_assign(&mut self, other: RHS, pow: u64);
}

Subtracts two numbers modulo $2^k$, in place. The inputs must be already reduced modulo $2^k$.

Required Methods

fn mod_power_of_2_sub_assign(&mut self, other: RHS, pow: u64)

Implementations on Foreign Types

impl ModPowerOf2SubAssign for u8

fn mod_power_of_2_sub_assign(&mut self, other: u8, pow: u64)

Subtracts two numbers modulo a third number $2^k$, in place. The inputs must be already reduced modulo $2^k$.

$x \gets z$, where $x, y, z < 2^k$ and $x - y \equiv z \mod 2^k$.

Worst-case complexity

Constant time and additional memory.

Panics

Panics if pow is greater than Self::WIDTH or if self or other are greater than or equal to $2^k$.

Examples
