Crate fast_factor 

A reasonably fast factorisation library for unsigned integers.

Examples

assert_eq!(fast_factor::factor(24_u32), vec![1,2,3,4,6,8,12,24]);
assert_eq!(fast_factor::proper_factor(24_u32), vec![1,2,3,4,6,8,12]);
assert_eq!(fast_factor::exclusive_factor(24_u32), vec![2,3,4,6,8,12]);
assert!(!fast_factor::is_prime(24_u32));

Functions

exclusive_factor

For all unsigned integer inputs, returns all factors of the number, excluding one and the number itself.

factor

For non-zero be unsigned integer inputs, returns all factors of the number given, including one and the number itself, as a vector. Returns an empty vector for zero.

is_prime

For all unsigned integer inputs, returns whether the number is prime. 0 and 1 are not.

proper_factor

For all unsigned integer inputs, returns all factors of the number, excluding the number itself.
