PRIMES

Purpose:

Generates a series of primes numbers in ascending order.

Syntax:

PRIMES(n)

n

-

An integer, the maximum prime value. The returned series contains prime numbers less than or equal to n.

Returns:

A series, the prime values less than or equal to n.

Example:

W1: primes(10)

 

W1 contains the series {2, 3, 5, 7}.

Example:

W1: primes(10)

W2: isprime(W1)

 

W2 contains the series {1, 1, 1, 1}, indicating that all the values of W1 are prime.

Remarks:

A prime number is a natural number (positive integer) with exactly two divisors, 1 and itself. Thus, 0 and 1 are not prime.
