Function solid_disk_moment_of_inertia 

pub fn solid_disk_moment_of_inertia(mass: f64, radius: f64) -> Option<f64>

Computes solid-disk moment of inertia using I = 0.5mr².

Returns None when mass or radius is negative, when any input is not finite, or when the computed moment of inertia is not finite.

Examples

use use_rotation::solid_disk_moment_of_inertia;

assert_eq!(solid_disk_moment_of_inertia(2.0, 3.0), Some(9.0));
