wide-word
A Haskell library providing Word128 and Int128 data types with all the
standard type class instances including Show, Read, Ord, Bounded,
Enum, Num, Bits, FiniteBits, Real, Integral, Storable and
NFData.
The Word128 type should be a drop in replacement for Word64 unless you are
specifically relying on the rounding/overflow/truncation behaviour of Word64.
