I believe this kind of generalized mathematical rounding is beyond the scope of NumberFormat, which engages in rounding only when necessitated by truncation. You can do what you need to do with Math.round() (by dividing and then multiplying), but offhand, I don't think there's any way to do it with NumberFormat. -- Shawn Bayern "JSTL in Action" http://www.jstlbook.com -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
