hello, I'm a newbie to Drools. I'm trying to write a rule that performs some math, without resorting to a function or eval. I searched the forum but found lots of posts on nested function calls,etc but not what I was searching for. For simplicity, lets assume I have the following classes public class ONE{ double A double B double C } public class TWO{ double D double E } where A, B, C, D, E are themselves calculated values (apr, price at some date, etc) 1. What does the LHS of a rule that compares A > D look like? 2. What does the LHS of a rule that compares A+B > C look like? 3. What does the LHS of a rule that compares A+D > C look like? I apologize in advance if this was covered already. Thanks. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/proper-syntax-for-mul...
