Description

Word256 implementation, with arithmetic written in C.

Should work on both little-endian and big-endian architectures, but only tested on little-endian.

Synopsis

Documentation

data Word256 Source #

Word256 is represented internally as 8 native 32 bit unsigned integers, in little-endian order.
