Number.parseInvariant Function

Number.parseLocale Function

Number extensions are part of the Microsoft Ajax Library. They add functionality to the JavaScript Number object and provide members that are more familiar to .NET programmers.

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);
