+/**
+ * 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.
