data- attribute with 18 digit or larger number

[mgramolini@…]

Every digit after the 17th comes back as a zero instead of its proper value.

I am not familiar with all the uses of isNumeric so I suggest only checking values for dataAttr function

line 1996: jQuery.isNumeric( data ) && data.length < ( data.indexOf('.') != -1 ? 18 : 17 ) ? parseFloat( data ) :

Otherwise, we could just not try to convert to a number.

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 with jQuery.fn.attr()}
