[JBoss JIRA] Created: (JBRULES-1322) Accumulate functions are highly unreliable for long's and BigDecimals

by Geoffrey De Smet (JIRA)

Accumulate functions are highly unreliable for long's and BigDecimals --------------------------------------------------------------------- Key: JBRULES-1322 URL: http://jira.jboss.com/jira/browse/JBRULES-1322 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: Drl Parser/Builder Affects Versions: 4.0.3 Reporter: Geoffrey De Smet Assigned To: Edson Tirelli Priority: Critical Fix For: 4.1.0 When dealing with financial data, one should never ever use double's. Instead BigDecimal should be used. Not because BigDecimal is bigger (that's rarely a problem) but because it doesn't do any decimal to binary transformation. For example, it's impossible for a double to correctly represent "0.2", aka 1/5. Summing many doubles (or even a few differing in scale), can easily give wrong results (and for financial data this tends to be important). Using doubles to sum longs have the exact same problem. Attached is a testcase patch which proves this by checking if (MAX_LONG - 4L) and 3L sum up to be (MAX_LONG - 1L). Currently they don't. One possible way to solve this is to fix JBRULES-1075, which just happens to give drools-solver 3% more performance ;) what a coincidence ^^ -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1199) Add a field constraint negation operator to drools

Add a field constraint negation operator to drools --------------------------------------------------- Key: JBRULES-1199 URL: http://jira.jboss.com/jira/browse/JBRULES-1199 Project: JBoss Rules Issue Type: Feature Request Security Level: Public (Everyone can see) Reporter: Arsalan Zaidi Assigned To: Mark Proctor Arsalan, Unfortunately Drools does not have a field constraint negation operator, mostly because when writing rules, it was not needed, since you can always negate the constraint itself. Although, I understand a agree with your use case. My suggestion is for you to open a JIRA feature request and we will include that as soon as possible in the product. Although, meanwhile, the only workaround I can see for your case is to translate the expression you are using directly into a java or mvel expression and write it inside an in-line eval. []s Edson 2007/9/14, Arsalan S. Zaidi <arsalan.zaidi(a)capgemini.com>: Hi I'll try to explain the situation that Gaurav finds himself in. We're working on this problem together and so far, we haven't been able to crack it. We're using drools to handle the business rules for an application. The rules however, are not provided to us in a .drl file, rather, we get an XLS sheet from the analysts with rules in a different grammar. We're using ANTLR to read and parse these rules to generate the drools rules programmatically. However, we're running into problems with NOT. The input rules (in the non-drools business language) have a NOT operator which works like '!' in Java. It flips the Boolean around, so to speak. So: NOT((some sub expression which evaluates to TRUE)) == FALSE MVEL doesn't seem to support this. So how do we simulate it? If it were only being used with NOT IN, we could manage, but its use is completely arbitrary. Changes to the input rules or to the input rules grammar have been (ha ha) ruled out. Any help would be appreciated.

You could also simplify the logic using DeMorgans Theorem (which might be troublesome to accomplish programmatically) I don't know whether your example is flawed as the brackets don't match, but assuming you mean something like this:- (NOT (G13.1 IN ("1","2","3") OR (G250.8 = Y))) You can re-write this as (G13.1NOT IN ("1","2","3") AND G250.8 != Y) With kind regards, Mike -------------------------------------------------------------------------------- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of JOSHI, GAURAV Sent: 13 September 2007 08:20 To: Rules Users List Subject: RE: [rules-users] How to use not operator in drool. Thank's for your sugession of using "not in" instead of "not" but my problem is that "not" can also come without "in". Actually I am making a generator of rule file from expression like ((NOT (ENDS WITH (G10.2, ","))) ((NOT (G13.1 IN ("1","2","3"))) OR (G250.8 = Y))) Where G13.2, G250.8, G10.2 are variables coming from a map inserted in working memory. I am accessing these variables from map. My rules are as follows This rule is working fine. rule "Editable_G10.3" when ((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19))) then System.out.println("comming here----------------------------------------------------->"); End This is not working rule "Mandatory_G10.3" when (not((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19)))) Then System.out.println("comming here----------------------------------------------------->"); End In also tried following approaches: 1) eval(not((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19)))) 2) eval(!((Map( this["G10.3"] !=8))||(Map( this["G10.2"] ==19)))) But in both cases it is giving same error: org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule name=ValidationRuleExp_G10.3, agendaGroup=MAIN, salience=0, no-loop=false] com/telekurs/nva/mde/fe/ak/validation/Rule_ValidationRuleExp_G10_3_0.java (11:495) : Cannot use this in a static context com/telekurs/nva/mde/fe/ak/validation/Rule_ValidationRuleExp_G10_3_0.java (11:500) : Type mismatch: cannot convert from String to int I am trying to find out some general concept so that I can change just achieve the functionality of not.
