pub fn is_prime(n: i64) -> bool

Returns true if the given number is prime.

Note that this solution is not efficient. If you want to test lots of and/or large numbers, use a more efficient solution.

Examples

let number = 23;
let answer = jabba_lib::jmath::is_prime(number);

assert_eq!(answer, true);
