aeq(..) method

aeq means "approximately equal".

    use float_plus::aeq;

    let a = 100.123_456_789;
    let b = 100.123_456_712;

    assert!(aeq(a, b, 6));
    assert!(!aeq(a, b, 7));

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);
