And what is the difference between fromIntegral and fromInteger ?
Integer is a specific single type: unlimited-precision integers.
Integral is a typeclass which includes, among others: Integer, Int
(integers represented in machine words, so either 32 or 64 bits), the
various Word* types defined in Data.Word (various fixed word sizes
such as Word8, as distinct from the hardware-preferred one
represented by Int), and the compatibility types defined in
Foreign.C.Types.
