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

As tymeJV mentioned, this looks like an issue with how jquery handles autoconversion. If you use "2", it gives a number as well, so I'm guessing its just a weird edge case in how they handle things. I would encourage just using .attr('xxx') and parsing out your data to its known type.
