`valueAsNumber` shim for Internet Explorer 11

valueAsNumber.js

(function () {
    
    /* Internet Explorer 11 may have trouble retrieving the number type
    of an input value. This short script performs a quick test, and repairs
    the functionality if necessary. Load before attempting to use the
    `valueAsNumber` property on input elements. */

    "use strict";

    var a = document.createElement( "input" );

    a.setAttribute( "type", "number" );
    a.setAttribute( "value", 2319 );

    if ( "valueAsNumber" in a && a.value != a.valueAsNumber ) {
        if ( "defineProperty" in Object && "getPrototypeOf" in Object ) {
            Object.defineProperty( Object.getPrototypeOf( a ), "valueAsNumber", {
                get: function () { return parseInt( this.value, 10 ); }
            });
        }
    }

}());

WTF is wrong with IE? OMG!!!

Thank you for your service to humanity good sir!

IE 10 as well btw

I'd suggest using parseFloat() if you need to deal with non-integers.

This works great. Now I will go to the local court house and legally change all my kids' names to 'Jonathan Sampson.' You rock.
