Trait FixedPowF

pub trait FixedPowF: Fixed {
    // Required method
    fn powf(self, n: Self) -> Self;
}

Extension trait providing fixed-point exponentiation for fixed-point numbers.

This is only implemented for types that can represent numbers larger than 1.

Required Methods

fn powf(self, n: Self) -> Self

Raises a number to a fixed-point power.

Panics

• If self is negative and n is fractional.

Examples

use fixed::types::I32F32;
use fixed_exp::FixedPowF;

let x = I32F32::from_num(4.0);
assert_eq!(I32F32::from_num(8.0), x.powf(I32F32::from_num(1.5)));

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.
