Unsigned integral types
This module provides unsigned integer types of unspecified width (
and fixed widths (
arithmetic is performed modulo 2^n, where
n is the number of bits in
For coercing between any two integer types, use
fromIntegral. Coercing word types to and from integer
types preserves representation, not sign.
The rules that hold for
Enum instances over a bounded type
Int (see the section of the Haskell language report dealing
with arithmetic sequences) also hold for the
over the various
Word types defined here.
Right and left shifts by amounts greater than or equal to the width of
the type result in a zero result. This is contrary to the behaviour
in C, which is undefined; a common interpretation is to truncate the
shift count to the width of the type, for example
1 << 32 == 1 in
some C implementations.
