Function glm::builtin::isnan

pub fn isnan<F: BaseFloat, B: GenBType, T: NumBoolRel<F, B>>(x: T) -> B

Returns true if x holds a NaN. Returns false otherwise.

Example

use glm::{ bvec3, dvec3, isnan };
use num::Float;

let nan: f64 = Float::nan();
assert!(isnan(nan));
assert_eq!(isnan(dvec3(nan, 1., -0.)), bvec3(true, false, false));
