The Lang library contains functions for absolute value calculations, data type manipulation, and random number generation.
| Function | Description |
| abort() | Aborts a WMLScript and returns a message to the caller of the script |
| abs(x) | Returns the absolute value of a number |
| characterSet() | Returns the character-set supported by the WMLScript interpreter |
| exit() | Exits a WMLScript and returns a message to the caller of the script |
| float() | Returns a Boolean value that indicates whether floating-point numbers are supported |
| isFloat() | Returns a Boolean value that indicates whether a value can be converted into a floating-point number by the parseFloat() function |
| isInt() | Returns a Boolean value that indicates whether a value can be converted into an integer by the parseInt() function |
| max(x,y) | Returns the number with the highest value of x and y |
| maxInt() | Returns the maximum possible integer value |
| min(x,y) | Returns the number with the lowest value of x and y |
| minInt() | Returns the minimum possible integer value |
| parseFloat() | Returns a floating-point value defined by a string |
| parseInt() | Returns an integer defined by a string |
| random(x) | Returns a random integer between 0 and x |
| seed() | Initializes the random number generator with a number, and returns an empty string |
Note: We think that the Lang library has a misleading name (should be named Math library or something like that). However, it is called the Lang library because it contains functions that are closely related to the core of the WMLScript engine.
