The Haskell Bit library in nhc98
This document describes the interface to the Bit library.

xor :: a -> a -> a -- bit-wise xor
compl :: a -> a -- bit-wise complement

(^>>) :: a -> Int -> a -- right shift
asr :: a -> Int -> a -- arithmetic right shift
rol :: a -> Int -> a -- rotate left
ror :: a -> Int -> a -- rotate right
test :: Int -> a -> Bool -- report n'th bit
