Function modulo 

pub fn modulo(x: f64, y: f64) -> f64

(fmod) Returns the floating-point remainder of x/y

The magnitude of the result is less than y and its sign agrees with that of x

Special cases

• modulo(±Inf, y) = NaN
• modulo(NaN, y) = NaN
• modulo(x, 0) = NaN
• modulo(x, ±Inf) = x
• modulo(x, NaN) = NaN

approx_eq(math::modulo( 5.3, 2.0), 1.3, 1e-15);
approx_eq(math::modulo(18.5, 4.2), 1.7, 1e-15);
