WMLScript Lang Library

The Lang library contains functions for absolute value calculations, data type manipulation, and random number generation.

WMLScript Lang Library Functions

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.
