WMLScript Lang Library

The Lang library contains a set of functions that are closely related to the WMLScript core.

The Lang Library

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()	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 true if floating-point numbers are supported, and false if not
isFloat()	Returns true if a specified value can be converted into a floating-point number by the parseFloat() function, and false if not
isInt()	Returns true if a specified value can be converted into an integer by the parseInt() function, and false if not
max()	Returns the largest value of two numbers
maxInt()	Returns the maximum possible integer value
min()	Returns the smallest value of two numbers
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()	Returns a random integer between 0 and a specified number
seed()	Initializes the random number generator with a number, and returns an empty string

Note: You may have noticed, that the Lang Library contains some functions that you would expect to find in a Math Library.

We think that the Lang Library has a slightly misleading name. But it is called the Lang Library because it contains functions that are closely related to the core of the WMLScript engine.

Also notice the existence of a Float Library.
