    use core::f64;

    let f = 3.7_f64;
    let g = 3.0_f64;
    let h = -3.7_f64;

    assert_eq!(f64::math::trunc(f), 3.0);
    assert_eq!(f64::math::trunc(g), 3.0);
    assert_eq!(f64::math::trunc(h), -3.0);

This standalone function is for testing only. It will be stabilized as an inherent method.
