Cannot compare int's division result to double ---------------------------------------------- Key: DROOLS-2391 URL: https://issues.jboss.org/browse/DROOLS-2391 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.4.1.Final Reporter: Viacheslav Krot Assignee: Luca Molteni I guess this is a bug - division of int fields in when part cannot be compared to double. For example with class A having two int fields following rule does not work when $a: A(a == 1, b == 2, a / b < 0.99) but this works: when $a: A(a == 1, b == 2, a / b < 1.0) Result of same expresson printed to output - System.out.println($a.a / $a.b) gives correct result of type Double. Why does it not work in when part?
