DivExpression

ffl::expression

Struct DivExpression 

Source 
pub struct DivExpression<L, R> {
    pub numerator: L,
    pub denominator: R,
}
Expand description

An expression representing deferred division.

Evaluations are deferred to preserve precision, scaling only when converted to a target resolution or assigned to a Fixed variable.

Fields§

§numerator: L

The numerator of the division expression.

§denominator: R

The denominator of the division expression.

Implementations§

Source§

impl<IL, const FL: usize, IR, const FR: usize> DivExpression<FastFixed<IL, FL>, FastFixed<IR, FR>>

Source

pub fn evaluate<I, const TARGET_FRAC: usize>(self) -> FastFixed<I, TARGET_FRAC>
where FastFixed<I, TARGET_FRAC>: From<Self>,

Evaluates the deferred division into a FastFixed value of the target format.

§Panics

Panics if the denominator is zero.
