Hello.

I have 4 bytes long String and i want to convert it to Float. How can i do this in Haskell? Don't want to use Ptr's.

Try this:

:m +Data.Array.IO Data.Word x <- newListArray (0,3) [0,0,40,66] :: IO (IOUArray Int Word8) y <- castIOUArray x :: IO (IOUArray Int Float) readArray y 0 >>= print 42.0
