Hi Daryoush, are you really looking for ByteString -> Float conversion, or just plain String -> Float? The latter is really simple, the function is called 'read' and is available in the Prelude: $ ghci GHCi, version 6.8.3: http://www.haskell.org/ghc/ :? for help Loading package base ... linking ... done. Prelude> read "3.14" :: Float 3.14 /Bjorn _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
