The WMLScript standard Lang library deals with mostly numbers and math. It includes the following functions: abs(), min(), max(), parseInt(), parseFloat(), isInt(), isFloat(), maxInt(), minInt(), float(), exit(), abort(), random(), seed(), and characterSet(). Go to Column 63, The Lang Library, to see a detailed definition of each function, including examples. Here is the definition of the abs() function:

Syntaxabs(value)
Parametersvalue = Number
ReturnsNumber or invalid
Examples:var a = -6;
var b = Lang.abs(a); // b = 6;
var c = -8.4;
var d = Lang.abs(c); // d = 8.4
