Macro nearly_eq::assert_nearly_eq

macro_rules! assert_nearly_eq {
    ($a:expr, $b:expr) => { ... };
    ($a:expr, $b:expr, $eps:expr) => { ... };
}

Asserts that two expressions are nearly(approximately) equal to each other.

You can optionally add an optional diff value. If you don't supply a diff value as an argument, NearlyEq::eps() is the default used.

Examples

assert_nearly_eq!(1f64, 1.5f64, 0.6f64); // does not panic
assert_nearly_eq!(0f64, 1e-12f64); // does not panic

assert_nearly_eq!(1f64, 2f64); // panics
