<p class="MsoNormal">The drl test case below illustrates a problem
with math
inside of drools when using the mvel dialect. When using autoboxing the
order
of operations (and parens) are not respected. This is using drools
5.0M1
and mvel-2.0-dp4.jar. The correct answer is 80 and the answer provided
with
autoboxing in the mvel dialect is 100.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m uncertain of how to create a viable test
case in
pure mvel to add it to their jira. Any help is appreciated,</p>

Drop in the newer MVEL, I believe this is fixed - if it's not open a
JIRA over at MVEL.<br>
