Unlike many langauges where Int is in the range 2 31 to 2 31 -1 using one bit for the sign bit, Haskell instead uses the range 2 29 to 2 29 -1 , or in other words 29 bits + 3 bits for something else... I'm guessing one of those three are the sign bit, but what then are the remaining two bits used for?

What does Int use three bits for?
