Macro expect_float_absolute_eq 

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

Expect the absolute error between two values is less than epsilon.

Returns an error if | a - b | > epsilon.

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

Examples

assert!(expect_float_absolute_eq!(3.0, 4.0, 1.0).is_ok());
assert!(expect_float_absolute_eq!(3.0, 4.0, 0.9).is_err());
assert!(expect_float_absolute_eq!(1.0, 0.5 + 0.5).is_ok());
