#9810: encodeFloat 1 2047 = -1024.0 -------------------------------------+------------------------------------- Reporter: luite | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.9 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: | Blocked By: None/Unknown | Related Tickets: #9811 Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by rwbarton): * related: => #9811 Comment: The old correct behavior depended somewhat precariously on being able to round-trip floating-point infinities through `toRational/fromRational`. This causes other wrong behavior, see #9811. While the situation with constant folding of floating-point is not ideal anyways, we should restore the old behavior of `toRational` (`decodeFloat`). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9810#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
