Right (sort of). Here's what the spec has to say about division:
Binary operator - A {/} B
If A and B are null, - return 0
Coerce both A and B to Double and apply operator
If operator results in exception, error
In addition, here's some info from java.text.DecimalFormat:
DecimalFormat uses half-even rounding (see ROUND_HALF_EVEN) for formatting.
So, as Matsuhashi suggests, here are a couple of things you could try with
<fmt:formatNumber>:
<%@ page contentType="text/plain" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt"; %>
<c:set var="var1" value="..."/>
<c:set var="var2" value="..."/>
<c:set var="var3" value="${var1 / var2}"/>
<c:out value="${var3}"/>
<fmt:formatNumber value="${var3}" pattern="#"/>
<fmt:formatNumber value="${var3}" maxFractionDigits="0"/>
If var1=12 and var2=5, you'll get:
2.4
2
2
However, if var1=21 and var2=6, you'll get:
3.5
4
4
Which may not be what you want if you really want integer division (truncation)...
