FUNCTION: Lang.abs
Lang.abs(value)
The Lang.abs function returns the absolute value of a specified
number. If the number is a floating-point, then an absolute floating-point
number is returned. If the number is an integer, then an absolute integer
will be returned.
Several functions in the Float Library can also be used to manipulate
numbers.
The mandatory value parameter can be any positive or negative single-precision
floating-point number or any positive or negative integer number (including
zero). The floating-point number must reside on or between the largest
number and the smallest nonzero number supported by the browser. These
boundary values can be determined using the Float.maxFloat and
Float.minFloat functions.
