Function approx_eq

pub fn approx_eq(a: f32, b: f32, e: f32) -> bool

Checks if two f32 values a and b are within e of each other.

This is useful for comparing floating point values, while allowing for some rounding errors.

Examples

assert_eq!(approx_eq(1.0, 1.01, 0.1), true);
assert_eq!(approx_eq(1.0, 1.3, 0.1), false);
