-----------------------------
> power operator needs specific typing for result
> -----------------------------------------------
>
> Key: GROOVY-7449
> URL: https://issues.apache.org/jira/browse/GROOVY-7449
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 2.4.3
> Reporter: Christopher Smith
> Assignee: Cédric Champeau
> Priority: Minor
>
> I wanted to use the power operator to set a static constant field:
> {code}
> public static final int DIGITS_IN_CODE = 4
> static final int mod = 10 ** DIGITS_IN_CODE
> {code}
> This results in a compile-time exception when used with {{@CompileStatic}}:
> {code}
> Groovy:[Static type checking] - Cannot assign value of type java.lang.Number
> to variable of type int
> {code}
> Replacing the symbolic constant with just {{10 ** 4}} produces the same bug.
> It appears that power expressions are not getting resolved until runtime even
> if they're compile-time constant expressions.
