.data() converting string to number

[[email protected]…]

I found a strange one. Grabbing a data attribute of an element with a certain value causes jQuery to convert the value to a number in scientific notation.

Example:

<script>$("#test").click(function(){alert($(this).data("code") + "\n" + $(this).attr("data-code"));});</script>
<a href="#" data-code="2309E34" id="test">Test</a>

The result is:
"2.309e+37
2309E34"

I have tested this is in Firefox V4, Chrome 10, and IE9 with the same result.

Sorry, I didn't see the notice about jsFiddle before. Here is a link to the test case I entered:
