FLoat Plus

aeq(..) method

aeq means "approximately equal".

    use float_plus::approx_eq::ApproxEq;

    let a = 100.123_456_789_f64;
    let b = 100.123_456_712_f64;

    assert!(a.aeq(b, 7));
    assert!(!a.aeq(b, 8));

RoundToFraction trait

    use float_plus::RoundToFraction;

    let before = 100.123_456_789_f64;
    let after = before.round_to_fraction(5);
    assert_eq!(after, 100.123_46);
