[jboss-jira] [JBoss JIRA] (JBRULES-3338) Accuracy lost when comparing numbers

Accuracy lost when comparing numbers ------------------------------------ Key: JBRULES-3338 URL: https://issues.jboss.org/browse/JBRULES-3338 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core (expert) Affects Versions: 5.3.0.Final Environment: sun jdk 1.6u27, drools 5.3.0 final Reporter: Miles Wen Assignee: Mark Proctor Accuracy lost when comparing two numbers which has different number types. for example: I have a pojo fact class 'Msg.java', and it has a int field named 'intVal', which value is inited 5. And I write down this rule and run with default settings: rule "out" when Msg(intVal == 5.5) then end this rule would fire! but it shouldn't, cause 5 != 5.5. It seems that drools converts the second operand of a comparison to the type of the first, no matter what the first number's type is. This definitely caused some accuracy lost in many cases. if I wrote Msg(5.5 == intVal), the code behaves correctly. -- This message is automatically generated by JIRA.
