Trait lair::Real

pub trait Real: Float {
    fn copysign(self, sign: Self) -> Self;
    fn recip(self) -> Self;
    fn eps() -> Self;
    fn sfmin() -> Self;
}

A trait for real numbers.

Required methods

fn copysign(self, sign: Self) -> Self

fn recip(self) -> Self

Takes the reciprocal (inverse) of a number.

fn eps() -> Self

Relative machine precision.

fn sfmin() -> Self

Safe minimum, such that its reciprocal does not overflow.
