   = x MOD y

The operator MOD divides two numbers and returns only the remainder. The result is the remainder after first expression is divided by the second expression. For example, the expression 14 MOD 4 evaluates to 2.

The result of a MOD operation will not retain the sign of any, and so it may be only positive. The result is always in the range [0, divisor), exclusive.

For example:

'8 Mod 3 = 2' '-8 Mod 3 = 2' '8 Mod -3 = 2' '-8 Mod -3 = 2'

If divisor evaluates to zero, the behavior of the MOD operator is to return the dividend as result, without sign.

  IF x MOD 2 THEN: PRINT "odd" : ELSE : PRINT "even": ENDIF
