Required Methods

fn mul_div_floor(self, num: RHS, denom: RHS) -> Self::Output

Calculates floor(val * num / divisor), i.e. the largest integer less than or equal to the result of the division.

fn mul_div_round(self, num: RHS, denom: RHS) -> Self::Output

Calculates round(val * num / divisor), i.e. the closest integer to the result of the division. If both surrounding integers are the same distance (x.5), the one with the bigger absolute value is returned (round away from 0.0).

fn mul_div_ceil(self, num: RHS, denom: RHS) -> Self::Output

Calculates ceil(val * num / divisor), i.e. the the smallest integer greater than or equal to the result of the division.

fn mul_shift_right(self, num: RHS, shift: u32) -> Self::Output

fn mul_shift_left(self, num: RHS, shift: u32) -> Self::Output

fn full_mul(self, num: RHS) -> Self::FullOutput
