HTML5 data-* attribute type casting strings and numbers

Question

Why is the value of data-value=\"2.0\" cast to a String and the value of data-value=\"2.5\" cast to a Number? I can handle this fine within my func

Answer 1

It appears to be treating that ".0" extension of the number like a string.

If all of your data values are going to be coming in in that format, just whip a parseFloat() on those suckers like this:

$("a").click(function() {
    alert(typeof parseFloat($(this).data( "value")));   
});

That way it won't matter if they are strings or numbers, they will always be treated like numbers(decimals intact).
