mod   operator



Syntax:
remainder = expr mod modulus

Description:
The mod operator subtracts from abs(expr) the largest multiple of abs(modulus) which is less than or equal to abs(expr), and returns the result as remainder. If expr is negative, then a negative result is returned in remainder.
Note that if expr and modulus are both integers, the result of mod is just the remainder of the integer division operation expr / modulus.
