Arithmetic
gcd
include math.e namespace math public function gcd(atom p, atom q)
returns the greater common divisor of to atoms.
Parameters:
 p : one of the atoms to consider
 q : the other atom.
Returns:
A positive integer, which is the largest value that evenly divides into both parameters.
Comments:
 Signs are ignored. Atoms are rounded down to integers.
 If both parameters are zero, 0 is returned.
 If one parameter is zero, the other parameter is returned.
Parameters and return value are atoms so as to take mathematical integers up to power(2,53).
Example 1:
? gcd(76.3, 114) > 38 ? gcd(0, 114) > 114 ? gcd(0, 0) > 0 (This is often regarded as an error condition)
