GHC supports various numeric literals such as decimal, octal, hexadecimal, binary, and floating point numbers. However, large numeric literals are hard to read. This proposal improves the readability, quality, expressiveness of numeric literals. This proposal allows underscores to numeric literals when the `NumericUnderscores` language extension is enabled. Underscores (`_`) in numeric literals are simply ignored. The specification of the feature is available here:\\ https://github.com/ghc-proposals/ghc-proposals/blob/master/proposals/0009 -numeric-underscores.rst For a discussion:\\ https://github.com/ghc-proposals/ghc-proposals/pull/76 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14473 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
