----------------------------------------------------------------
I'm doing work with (digital) currency and am seeking to avoid any rounding or
truncation, so am looking at everything with an eagle eye. Note that JSR-354
(Java Money) include a subclass of {{Number}} called
[NumberValue|https://github.com/JavaMoney/jsr354-api/blob/master/src/main/java/javax/money/NumberValue.java]
that adds methods named {{longValueExact()}}, {{doubleValueExact()}}, etc.
that throw {{ArithmeticException}} if truncation would have occurred.

> Key: GROOVY-7385
> URL: https://issues.apache.org/jira/browse/GROOVY-7385
> Project: Groovy
> Issue Type: Bug
> Components: syntax
> Affects Versions: 2.4.3
> Environment: Mac OS X
> Reporter: Sean Gilligan
> Assignee: Jochen Theodorou
>
> 2147483648I should be an invalid Integer literal.
> 9223372036854775808L should be an invalid Long literal.
> Both currently compile (and produce an unexpected value -- well, it would be
> the expected value in 2's complement math)
> I created some unit tests to show the problem -- not sure if I put them in
> the right place, but they do fail as I expect them to.
