#10364: Feature request: Add support for FMA -------------------------------------+------------------------------------- Reporter: lerkok | Owner: ekmett Type: feature request | Status: new Priority: normal | Milestone: Component: Core Libraries | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by ekmett): This probably should go out through a standard libraries@ proposal process first, to get a sense of how willing the community would be to accept a change that far up the chain. You may get some horribly long `fusedMultiplyAdd` name though. =) I could definitely see putting it in RealFloat. We had a proposal last year for adding things like `expm1` and `log1p`, etc. which passed, which will involve adding members nearby. Warning though: when we lobbied for `expm1` the comunity pushed back against having sensible defaults like the one you mention here and preferred leaving it undefined, to prompt people to fill them in proactively. I'm not sure that is/was a good idea, but some folks fought pretty hard against defaults that might lose precision favoring bottoms instead. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10364#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
