jQuery.fn.data()converts all string values into real JavaScript primitive and object values (string, number, boolean, object, array etc). Given this information and knowing that the largest finite integral number in JavaScript is 2^53, or 9007199254740992 (try adding 1 to that number, it won't work), which is 16 characters long, we can assume that numbers of that length will not be valid in JavaScript. If you need the full value, access withjQuery.fn.attr()
