For more information about the JavaScript object that this type extends and about its constructor, see JScript Number Object in the Language Reference.

Example

The following example shows how to call the ASP.NET AJAX parseInvariant extension function to create a number from the string representation of a number.

var a = Number.parseInvariant("4");
var b = new Number(2);
var c = Number.parseInvariant("1.53") + a + b;
// View the results: "7.53"
alert(c);
