[rules-users] Writing calculation in .drl

[Joshua Jackson]

Dear all,

I've tried writing calculation within function or the rules block but
it seems can not run. I also could not find any examples that has
calculation in .drl file. Would it be possible to have calculation
within .drl, or do we have to write a method within .java file for the
calculation

Thanks in advance
