#16216: readHexRational missing from Numeric -------------------------------------+------------------------------------- Reporter: merijn | Owner: (none) Type: feature | Status: new request | Priority: normal | Milestone: Component: | Version: 8.6.3 libraries/base | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- The HexFloatLiterals extension was merged as result of https://github.com /ghc-proposals/ghc-proposals/blob/master/proposals/0004-hexFloats.rst As part of this proposal `showHFloat` was added to Numeric to output floating points in hexFloat format, unfortunately, no one seems to have remembered to add `readHexRational` or a similar function to parse hexFloats to Numeric. This leads to the awkward scenario that I can easily produce hexFloat values, but have no way to parse them from `String`/`Text` data... All the code already exists in `compiler/util/Utils.hs`, someone just needs to cherry pick the implementation add add it to Numeric in base. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16216 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
