Function angular_momentum 

pub fn angular_momentum(
    moment_of_inertia: f64,
    angular_velocity: f64,
) -> Option<f64>

Computes angular momentum using L = Iω.

Returns None when moment_of_inertia is negative, when any input is not finite, or when the computed angular momentum is not finite.

Examples

use use_rotation::angular_momentum;

assert_eq!(angular_momentum(4.0, 5.0), Some(20.0));
