#8539: Data.Complex shouldn't use default implementation of (**) -------------------------------------+------------------------------------- Reporter: jjaredsimpson | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Prelude | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: Incorrect result | Difficulty: Easy (less than 1 at runtime | hour) Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------- Comment (by isaacdupree): That solves `0**nonzero`. `0**0` is controversial but often 1 ( https://en.wikipedia.org/wiki/0^0 ) and in Double is 1: {{{
0**0 :: Double 1.0 }}} We probably want `0**0` to be consistent between Double and Complex Double.
