A Utility Library for Logical Variables

**L4LIB**
is a Python library which
contains many utility routines for "L4" or "one byte logical"
arithmetic.

The computer code and data files made available on this web page are distributed under the GNU LGPL license.

**L4LIB** is available in
a C version and
a C++ version and
a FORTRAN90 version and
a MATLAB version and
a Python version.

C4LIB, a Python library which implements certain elementary functions for single precision complex (C4) variables.

C8LIB, a Python library which implements certain elementary functions for "C8" or double precision complex variables;

I4LIB, a Python library which contains many utility routines, using "I4" or "4 byte integer" arithmetic.

R8LIB, a Python library which contains many utility routines, using "R8" or "double precision real" arithmetic.
