Function glm::builtin::ldexp [−] [src]

pub fn ldexp<F: BaseFloat, G: GenFloat<F>, T: IntFloatRel<i32, F, G>>(
    x: G, 
    exp: T
) -> G

Builds a floating-point number from x and the corresponding integral exponent of two in exp, returning: significand ⋅ 2^exponent.

If this product is too large to be represented in the floating-point type, the result is undefined.

Example

use glm::{ ldexp, vec3, ivec3 };

assert_eq!(ldexp(2_f32, 2), 8.);
let vf = vec3(1., 2., 3.);
let vi = ivec3(-1, 1, 2);
assert_eq!(ldexp(vf, vi), vec3(0.5, 4., 12.));
