how to apply mathematic in a jsp page

[shoa]

Hello

I have an object house that canbe displayed in a jsp as:
<td> ${house.rentYear} </td>

It works OK.

Now I want to display also the price per month in this jsp (for viewing only). So I need to get the value of rentYear/12.

Could you please tell me how to do that

Many thanks

Doesn't ${house.rentYear / 12} work?

Use the fmt tag library from JSTL. E.g.:


<fmt:formatNumber pattern="###,##0.00" value="${hour.rentYear/12}"/>


You can specify minimum and maximum number of digits, along with various other things. You'll need to have the following at the top of your JSP, just as with the core (c:) library):


<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

Check out the format tag (part of sun's core tags): http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/overview-summary.html
