NAME

contextInteger.pl - adds integer related functions primeFactorization, phi, tau, isPrime, randomPrime, lcm, and gcd.

DESCRIPTION

This is a Parser context that adds integer related functions. This forces students to only enter integers as their answers.

Context("Integer")

Generate an array of each prime factor

@a = primeFactorization(1000);
ANS(List(@a)->cmp);

Get the gcd

$b = gcd(5, 2);
ANS($b->cmp);

The the lowest common multiple:

$c = lcm(36, 90);
ANS($c->cmp);

Find phi

$d = phi(365);
ANS($d->cmp);

Find tau

$e = tau(365);
ANS($e->cmp);

Check if prime

$f = isPrime(10); #False
$h = isPrime(5); #True

Get a random prime in a range

$randomPrime = randomPrime(100, 1000);

Find the prime factorization of an integer.

Find the greatest common divisor

Find the lowest common multiple.

Find phi.

Find tau.

Determine if the given integer is prime.
