Function ladderz::pre_algebra::is_prime

source · 
pub fn is_prime(n: u32) -> bool
Expand description

Checks if a positive integer n is a prime number.

+

A prime number is a positive integer greater than 1 that cannot +be evenly divisible by any positive integers other than 1 and itself.

+

Examples

+
use ladderz::pre_algebra::is_prime;
+
+assert!(!is_prime(1)); // 1 is not a prime number
+assert!(is_prime(2)); // 2 is a prime number
+assert!(!is_prime(4)); // 4 is not a prime number
+assert!(is_prime(7)); // 7 is a prime number
+

Note

+

This function returns false for values of n less than 2 because, by definition, prime +numbers must be greater than 1.
