I am trying to convert a string to a float. It seems that Data.ByteString library only supports readInt. After some googling I came accross a possibloe implementation: [1]http://sequence.svcs.cs.pdx.edu/node/373
Use the bytstring-lexing library,
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/bytestring-lexing
Which provides a copying and non-copying lexer for doubles,
readDouble :: ByteString -> Maybe (Double, ByteString) unsafeReadDouble :: ByteString -> Maybe (Double, ByteString)
Incidentally, is there any reason we can't have this for Lazy BSes? Bob
