I want to convert Float to a list of bytes [Word8] (and vice versa). I see there is a Storable class which could maybe be used for this, but I’d like to avoid using IO monad as this has nothing to do with IO.

What is it that you want? If you want to convert between the Float and its actual bit representation, you can use data-binary-ieee754 (uses
Foreign.StorableandunsafePerformIOunder the hood) or cereal-ieee754. The latter doesn’t useStorableorIO, it writes the value to anSTUArray, casts the array and reads a value of the other type. Both packages give you a conversionFloat <-> Word32(orDouble <-> Word64), converting theWordNto[Word8]is easy.
