in JSP: rounding values
Hi,
I want to round a value during an interation:
------------------------------------------
<s:sort comparator="mapComparator" source="statsMap">
<s:iterator>
<tr>
<td><s:property value="key.name" /><br>(Min: <s:property value="key.min"
/>, Max: <s:property value="key.max" />)</td>
<td>
<s:set name="average" value="value.average" />
<%
int val = 0;
%>
<s:property value="val" />
</td>
</tr>
</s:iterator>
</s:sort>
------------------------------------------
As you can see, I iterate over a map. The value element of the map contains
a field named "averate". This average is a Float which I want to round
(Math.round()). I don't really know how to do that. I can find out how to
access the value from within <% %>. Once I have access to it, how can I
print that value? I never actually used <% %> tags.
Or ist there an easier way?
The whole idea if this code is to display ratings of serveral criteria where
a rating has a minimum value of key.min, a maximum of key.max and the
average rating is value.average. I want these values to be displays using
star icons. I am telling you this hoping there is a much easier way ;)

It even will be faster than searching for some strange solution with
Struts2 Tags ;-)

As you thing, but that's the business logic and even such simple
operation shouldn't be performed in UI. Maybe it will be simpler to
create TransferObject with original value and rounded value and put it
on the list.

I don't think so - I want the exact value to be shown, too, so it's more a UI
thing.

Maybe it will be better to prepare a list on server side with rounded
values and iterate over them?
