Subject [jira] [Created] (NUMBERS-65) "RootsOfUnity" vs "nthRoot"
Date Fri, 02 Feb 2018 14:38:00 GMT
Gilles created NUMBERS-65:
-----------------------------

             Summary: "RootsOfUnity" vs "nthRoot"
                 Key: NUMBERS-65
                 URL: https://issues.apache.org/jira/browse/NUMBERS-65
             Project: Commons Numbers
          Issue Type: Task
          Components: complex
            Reporter: Gilles
             Fix For: 1.0


There is partial overlap of functionality between class {{RootsOfUnity}} and method {{nthRoot}}
(in class {{Complex}}).

The latter is more general (any complex number) but the former allows a negative argument
(to specify clockwise ordering).

Also, the implementations are different; it should be checked which is more accurate (and
then account for possible performance trade-offs).

API-wise, I think that we should keep {{nthRoot}} (and delete {{RootsOfUnity}}).
