Julien Aymé commented on JEXL-143:
----------------------------------
I think that the way the expression is written (2^62), it is evaluated to a
double and then cast into long, which results to the rounding observed.
Could you try with the following expression instead : 1L << 62, it should be
allright (wild guess here, cannot try it atm).

> Key: JEXL-143
> URL: https://issues.apache.org/jira/browse/JEXL-143
> Project: Commons JEXL
> Issue Type: Improvement
> Affects Versions: 2.1.1
> Environment: Ubunu 12.04, android studio 0.2.10
> Reporter: Frank
>
> When calculating huge numbers, which are still in the long range the result
> is wrong (or getting rounded somehow), e.g.
> Expression e = jexl.createExpression("2^62");
> JexlContext context = new MapContext();
> String res = String.valueOf(e.evaluate(context));
> returns `4611686018427388000` but it should be `4611686018427387904`
