Function glm::builtin::usubBorrow

pub fn usubBorrow<T: GenUType>(x: T, y: T) -> (T, T)

Subtracts the 32-bit unsigned integer y from x, returning the difference and the borrow bit.

Returns the difference if it is non-negative, or 2³² plus the difference otherwise.

The borrow bit is set to 0 ifx ≥ y, or to 1 otherwise.

Example

use glm::{ usubBorrow, uvec2 };

let uv1 = uvec2(16, 17);
let uv2 = uvec2(17, 16);
assert_eq!(usubBorrow(uv1, uv2), (uvec2(0xFFFFFFFE, 1), uvec2(1, 0)));
