I have an html like this:

<input type="radio"
 class="class" 
 name="attr" 
 value="value" 
 data-identifier="13309600171026321254"/>

When I try to retrieve the identifier data attribute it recognizes it as a number and parse it, but it rounds the last part:

$("input.class").data("sku") 
// -> 13309600171106320000

If I try to parse the string as an int I have the same result:

parseInt("13309600171026321254")
// -> 13309600171106320000

I assume it's a bug on parseInt function but this kind of errors could be detected and then return the original string instead of trying to parse it.
