Henri Biestro resolved JEXL-242.
--------------------------------
Resolution: Cannot Reproduce
Following code does not reproduce:
{code}
@Test
public void test242() throws Exception {
Double a = -40.05d;
Double b = -8.01d;
Double c = a + b;
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 e = (Double) jsp.evaluate(context);
Assert.assertTrue(Double.doubleToLongBits(e) + " != " +
Double.doubleToLongBits(c), c.doubleValue() == e.doubleValue());
Assert.assertTrue(Double.doubleToLongBits(e) + " != " +
Double.doubleToLongBits(c), a + b == e);
}

> 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
> Assignee: Henri Biestro
> 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
