We wrote a readInt a long time ago, because we needed it. It turns out that really though, there's a large class of functions for parsing bytestrings should come with, so I've started adding those to the bytestring-lexing package. In hindisight ByteString.readInt should have been in a separate package. -- Don dmehrtash:
I am curious to understand the logic, the "Haskell Think", here. Why is it that the byteString only supports conversion to int.

Use the bytstring-lexing library,
[3]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) -- Don
