Macro assert_float_relative_ne 

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

Assert the relative error between two values is greater than epsilon.

Panics if |(a - b) / a| <= epsilon. If a.is_infinite(), then this will always panic. If a.is_nan(), then this will never panic.

• a - First float.
• b - Second float.
• epsilon - Relative error tolerance between floats (defaults to 1.0e-6).

Examples

assert_float_relative_ne!(4.0, 3.0, 0.25 - 1.0e-7);
assert_float_relative_ne!(1.0, 0.5 + 0.5 + 1e-5);
