isPrime(a)

Determines if a number is prime.

Syntax

o_isPrime(a): a: scalar Integer - number to be tested; return: boolean - 0=not prime, 1=prime

Usage

Use whenever you would like to test a number to see if it is prime. A typical use would be to generate a set of primes for factorization.

Location

menu: veeos ==> Math ==> isPrime

library: mathLib

Example

o_isPrime(4) returns 0
o_isPrime(99961) returns 1

Notes

The algorithm used here is fairly brute-force but as such as about foolproof. While it is reasonably fast , it would not be appropriate to use for extremely large values.
