> When I study drools , I write a rule use divide operator
> {code:java}
> rule "Buzz" salience 2
>  when
>   $n: Number( this / 5 == 3 )
>  then
>   System.out.println("Buzz");
> end

> It's OK.
> But:
> {code:java}
> rule "Buzz" salience 2
>  when
>   $n: Number( this % 5 == 0 )
>  then
>   System.out.println("Buzz");
> end
> {code}
> Report parser error: Unable to Analyse Expression this % 5 == 0:
> The drools document mentioned the same example:
> Person( age > 100 && ( age % 10 == 0 ) )
> % is Multiplicative operators, why parser error?
