Struct libm::Libm

source · 
pub struct Libm<T>(_);
Expand description

Generic helper for libm functions, abstracting over f32 and f64.

Type Parameter:

  • T: Either f32 or f64

Examples

use libm::{self, Libm};

const PI_F32: f32 = 3.1415927410e+00;
const PI_F64: f64 = 3.1415926535897931160e+00;

assert!(Libm::<f32>::cos(0.0f32) == libm::cosf(0.0));
assert!(Libm::<f32>::sin(PI_F32) == libm::sinf(PI_F32));

assert!(Libm::<f64>::cos(0.0f64) == libm::cos(0.0));
assert!(Libm::<f64>::sin(PI_F64) == libm::sin(PI_F64));
