[jboss-jira] [JBoss JIRA] (DROOLS-674) Rules with bigdecimal comparison not matched for certain values

[Mario Fusco (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-674?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mario Fusco resolved DROOLS-674.
--------------------------------
    Resolution: Rejected


If you write 69.99 you're in reality saying that the value is a double with all the rounding issues it implies. 
Saying explicitly that it is a BigDecimal (writing it as 69.99B) fixes the problem.

> For rules which compare BigDecimal inputs against a range considering 2 decimal place precision, match does not happen when the input equals certain upper bounds. Testcase attached. 
> The rules match when the upper bound is specified with a < condition instead of <= (i.e <70.00 instead of <=69.99) , which seem to indicate value seen by Drools is somewhere between the two. 
> Envrionment:
> Drools : 5.5.0.Final
> Java version : Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
> OS : CentOS release 6.1 (Final)
