19.4. Calculating the Absolute Value of a Numeric Value: abs() Function
The abs() function is used to calculate the absolute value of a certain numeric value. If any error occurs, it returns invalid. The following WMLScript example demonstrates the use of abs():
x
= Lang.abs(-100);
y = Lang.abs(100);
z = Lang.abs(-2.55);
After the execution of the above script, x and y have the integral value 100 while z has the floating-point value 2.55.
