This behaviour is not what I expect after reading the description at http://haskell.org/ghc/docs/latest/html/libraries/base/Prelude.html#v:round . Given that this behaviour has caused a bit of confusion I think a change to the documention might be in order. /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe
