> 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
