BVEC
Binary Vector Representation of Signed Integers
BVEC
is a C library which
demonstrates how signed integers can be stored as
binary vectors, and arithmetic can be performed on them.

a C library which
demonstrates how unsigned binary vectors, strings of 0's and 1's,
can represent nonnegative integers or subsets or other mathematical
objects, for which various arithmetic and logical operations can
be defined.
