#14377: some results not expected with the addition -------------------------------------+------------------------------------- Reporter: vanto | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: invalid | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by svenpanne): Just a few more hints why this is not a bug (all from the Haskell Report): * Numerical literals with a dot in it have an implicit `fromRational` around it. * Not surprisingly, `fromRational` forces its 1st argument to be a `Rational`. * The default default is `default (Integer, Double)`. * `(**) :: Floating a => a -> a -> a`. With that information you can figure out why e.g. the division in a) is a different kind of division than the one in b). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14377#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
