firefox's javascript engine fails to return a simple result from a multiplication between an integer and a float.

Reproducible: Always

Steps to Reproduce:
Create a page with the following code:
<input type="button" onclick="alert(6 * 1.66)" />
It will return 9.95666666666666 instead of 9.96.

Actual Results:  
9.956666666666

Expected Results:  
9.96

If you multiply with 60 or with 600 instead of 6, you get the expected results.
