#14818: Provide highestOneBit function in Data.Bits module -------------------------------------+------------------------------------- Reporter: kostmo | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 8.2.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): If I understand correctly, we already have these: * `countLeadingZeros` is `GHC.Prim.clzN#`, which is exposed by `Data.Bits.countLeadingZeros`. * `highestOneBit` is `GHC.Prim.ctzN#`, which is exposed by `Data.Bits.countTrailingZeros` -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14818#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
