WMLScript arithmetic operators can help you perform various kinds of math operations.
Basic math operations like addition, subtraction and multiplication are done using the +, - and * operators. For example:
z = 1 + 2;
z has the value 3.
z = 5 - 3;
z has the value 2.
z = 2 * 3;
z has the value 6.
Two operators, / and div, can be used to perform division. The result returned by the / operator is of the float type and that returned by the div operator is of the integer type. Here is a WMLScript example that illustrates the difference between them:
= 3 / 2;
y = 3 div 2;
After execution, x has the floating-point value 1.5 while y has the integral value 1.
To find the remainder of division, use the % operator. For example:
= 3 % 2;
y = 20 % 2;
z = 20 % 3;
After execution, x has the value 1, y has the value 0 and z has the value 2.
