Trait easy_cast::ConvFloat

pub trait ConvFloat<T> {
    fn conv_nearest(x: T) -> Self;
    fn conv_floor(x: T) -> Self;
    fn conv_ceil(x: T) -> Self;
}

Nearest / floor / ceil conversions from floating point types

This trait is explicitly for conversions from floating-point values to integers.

If the source value is out-of-range or not-a-number then the conversion must fail with a panic.

Required methods

fn conv_nearest(x: T) -> Self

Convert to the nearest integer

Half-way cases are rounded away from 0.

fn conv_floor(x: T) -> Self

Convert the floor to an integer

Returns the largest integer less than or equal to x.

fn conv_ceil(x: T) -> Self

Convert the ceiling to an integer

Returns the smallest integer greater than or equal to x.
