math.modulo ViewHelper <vhs:math.modulo>

Math: Modulo Perform modulo on $input. Returns the same type as $input, i.e. if given an array, will transform each member and return the result. Supports array and Iterator (in the following descriptions "array" means both these types):

If $a and $b are both arrays of the same size then modulo is performed on $a using members of $b, by their index (so these must match in both arrays).

If $a is an array and $b is a number then modulo is performed on $a using $b for each calculation.

If $a and $b are both numbers simple modulo is performed.
