public Number(num:Object)
Creates a new Number object. The new Number constructor is primarily used as a placeholder.
A Number object is not the same as the
Number() function that converts a parameter to a
primitive value.
Availability: ActionScript 1.0; Flash Lite 2.0
Parameters
num:Object - The numeric value of the Number object being created or a value to be
converted to a number. The default value is 0 if
value is not provided.
Example
The following code constructs new Number objects:
var n1:Number = new Number(3.4);
var n2:Number = new Number(-10);

property)
public static POSITIVE_INFINITY : Number
Specifies the IEEE-754 value representing positive infinity. The value of this property is the
same as that of the constant

Positive infinity is a special numeric value that is returned when a mathematical operation or
function returns a value larger than can be represented.

Example
This example compares the result of dividing the following values.
var posResult:Number = 1/0;
if (posResult == Number.POSITIVE_INFINITY) {
trace("posResult = "+posResult); // output: posResult = Infinity
}
var negResult:Number = -1/0;
if (negResult == Number.NEGATIVE_INFINITY) {
trace("negResult = "+negResult); // output: negResult = -Infinity
