Subject [jira] [Commented] (NUMBERS-65) "RootsOfUnity" vs "nthRoot"
Date Thu, 19 Apr 2018 13:01:00 GMT


Gilles commented on NUMBERS-65:

bq. I think this is the one to use.

OK, let's keep that one and move on. :)

bq. expanded to handle a negative integer as going the other direction.

Will you update the implementation of {{nthRoot}} (and unit tests)?

> 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}}).
