Trait MulDiv

    // Required methods
    fn checked_mul_div(
        &self,
        numerator: &Self,
        denominator: &Self,

Perform Mul-Div calculation with bigger range num type.

Required Methods

fn checked_mul_div(&self, numerator: &Self, denominator: &Self) -> Option<Self>

Calculates floor(self * numerator / denominator) with full precision.

Returns None if the denominator is zero or overflow.

fn checked_mul_div_ceil( &self, numerator: &Self, denominator: &Self, ) -> Option<Self>

Calculates ceil(self * numerator / denominator) with full precision.

Returns None if the denominator is zero or overflow.

Provided Methods

fn checked_mul_div_with_signed_numerator( &self, numerator: &Self::Signed, denominator: &Self, ) -> Option<Self::Signed>

Calculates floor(self * numerator / denominator) with full precision, where numerator is signed.

Returns None if the denominator is zero or overflow.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
