Examples

extern crate octoon_math;

use octoon_math::*;
use octoon_math::consts::*;

fn main()
{

    let a = float2::new(1.0,0.0);

// new float3
    let c = float3::new(1.0,0.0,0.0);
    let d = float!(0.0,1.0,0.0); // same as float3::new

// new float4
    let e = float4::new(1.0,0.0,0.0,0.0);
    let f = float!(0.0,1.0,0.0,0.0); // same as float4::new
