#4867: ghci displays negative floats incorrectly (was: Incorrect result from trig functions) -------------------------------+-------------------------------------------- Reporter: gwright | Owner: gwright Type: bug | Status: new Priority: high | Milestone: 7.0.2 Component: GHCi | Version: 7.0.1 Keywords: | Testcase: Blockedby: | Difficulty: Os: MacOS X | Blocking: Architecture: x86_64 (amd64) | Failure: Incorrect result at runtime -------------------------------+--------------------------------------------
Comment(by altaic): Hmm, that's odd... Perhaps someone with better GHC-fu can figure out why these results are different: {{{ Prelude GHC.Float> showsPrec 0 (-1.0 :: Double) "" "--1.0" Prelude GHC.Float> showSignedFloat showFloat 0 (-1.0 :: Double) "" "-1.0" }}} Given that in `Float.lhs`: {{{ instance Show Double where showsPrec x = showSignedFloat showFloat x showList = showList__ (showsPrec 0) }}} -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/4867#comment:31> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
