Function almost_equal_f64

pub fn almost_equal_f64(a: f64, b: f64, epsilon: f64) -> bool

Return true when arguments are the same within some rounding error.

For instance almost_equal(x, x.to_degrees().to_radians(), f64::EPSILON) should hold true for all x. The epsilon can be f64::EPSILON to handle simple transforms (like degrees -> radians) but should be higher to handle more complex transformations.
