It seems the printing of -0 has changed. Here's my session
{{{ $ ghci GHCi, version 7.8.3: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. Prelude> let x = -0 Prelude> x 0 }}}
This part is just because `x` defaulted to Integer on this line; `-0.0` is still printed as `-0.0`. (7.8.3 has the MR disabled in ghci by default.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8780#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
