a floating point literal like 1e100 means fromRational (n % d) where "the integers n and d are chosen so that n/d = f"
But finding the n and d should happen after type checking, no? Why idoes this even effect type checking time? Shouldn't `:t` just do type checking? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15646#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
