Paul King closed GROOVY-9999.
-----------------------------
> @TypeChecked results in Error when groovy casts to BigDecimal ([Static type
> checking] - Cannot find matching method
> java.lang.Math#sqrt(java.math.BigDecimal))
> --------------------------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: GROOVY-9999
> URL: https://issues.apache.org/jira/browse/GROOVY-9999
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.5.11, 3.0.7, 4.0.0-alpha-2
> Reporter: Andreas Vorgeitz
> Priority: Critical
> Fix For: 4.0.5
>
> Attachments: TypeChecker.groovy
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> From Groovy >2.4 simple calculations cannot be @TypeChecked without loads of
> casting:
> {{import groovy.transform.TypeChecked}}
> {{@TypeChecked}}
> {{def test() {}}
> {{ Math.sqrt(Math.PI*2)}}
> {{}}}
> => [Static type checking] - Cannot find matching method
> java.lang.Math#sqrt(java.math.BigDecimal). Please check if the declared type
> is correct and if the method exists.
> in Groovy 2.4 this was valid code.
> I was able to write a TypeChecker, but it looks pretty ugly and i am not
> shure, that this does not add other complications.
> Since most of my colleagues are not groovy mains, i prefer forcing the
> TypeChecker, but this would lead to permanent castings from BigDecimal to
> double before calling any method.
> Any better workaround or a fix is appreciated.
