#10754: truncate /= double2Int -------------------------------------+------------------------------------- Reporter: cblp | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 7.10.2 Resolution: | Keywords: truncate, | double2Int, rewrite, rule Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by cblp): Speaking mathematically, yes, as 1/0 is actually +infinity, nearest Int is maxBound, and for (-1/0) the nearest Int is minBound. But what is the correct answer for {{{truncate (1/0) :: Integer}}}? Now it is 179769313486231590772930519078902473361797697894230657273430081157732675805500963132708477322407536021120113879871393357658789768814416622492847430639474124377767893424865485276302219601246094119453082952085005768838150682342462881473913110540827237163350510684586298239947245938479716304835356329624224137216. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10754#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
