Binary Vector Representation of Signed Integers
is a FORTRAN77 library which
demonstrates how signed integers can be stored as
binary vectors, and arithmetic can be performed on them.
The computer code and data files made available on this
web page are distributed under
the GNU LGPL license.
BVEC is available in
a C version and
a C++ version and
a FORTRAN77 version and
a FORTRAN90 version and
a MATLAB version and
a Python version.

BVEC_COMPLEMENT2 computes the two's complement of a binary vector.
BVEC_MUL computes the product of two binary vectors.
BVEC_NEXT generates the next BVEC.
BVEC_NOT "negates" or takes the 1's complement of a binary vector.
BVEC_OR computes the inclusive OR of two binary vectors.

BVEC_TO_I4 makes an integer from a (signed) binary vector.
BVEC_UNIFORM returns a pseudorandom BVEC.
BVEC_XOR computes the exclusive OR of two binary vectors.
I4_TO_BVEC makes a signed binary vector from an I4.
I4_UNIFORM_AB returns a scaled pseudorandom I4.
TIMESTAMP prints the current YMDHMS date as a time stamp.
