Dmitri Blinov commented on JEXL-242: ------------------------------------ You can check if jexl works correctly by evaluating your arithmetic in plain java. Double a = -40.05; Double b = -8.01; Double c = a + b > invalid jexl calculation while doing sum for particular value > ------------------------------------------------------------- > > Key: JEXL-242 > URL: https://issues.apache.org/jira/browse/JEXL-242 > Project: Commons JEXL > Issue Type: Bug > Affects Versions: 3.1 > Reporter: vikas garg > Priority: Blocker > > For a particular value of 0.05 , jexl is returning value unxepectedly > I have face an issue with following calcualtion: > Double a = -40.05; > Double b = -8.01; > final JexlContext context = new MapContext(); > context.set("a",a); > context.set("b",b); > JexlEngine JEXL_ENGINE = new JexlBuilder().strict(true).silent(true).create(); > JexlExpression jsp = JEXL_ENGINE.createExpression("a+b"); > Double c = jsp.evaluate(context); > The value returned by evaluation is -48.059999999999995 instead of -48.06 > There seems some precision issue in calculation -- This message was sent by Atlassian JIRA (v6.4.14#64029)
