Exponentiation for fixed-point numbers.

[dependencies]
fixed-exp = "0.1.0"

Usage

This crate provides powi and powf for most fixed number types through the FixedPowI and FixedPowF extension traits:

use fixed::types::I32F32;
use fixed_exp::{FixedPowI, FixedPowF};

let x = I32F32::from_num(4.0);
assert_eq!(I32F32::from_num(1024.0), x.powi(5));
assert_eq!(I32F32::from_num(8.0), x.powf(I32F32::from_num(1.5)));
