Credit also goes to:

* The authors of the GMP library and the Python wrapper
  gmpy, enabling mpmath to become much faster at
  high precision
* The authors of MPFR, pari/gp, MPFUN, and other arbitrary-
  precision libraries, whose documentation has been helpful
  for implementing many of the algorithms in mpmath
* Wikipedia contributors; Abramowitz & Stegun; Gradshteyn & Ryzhik;
  Wolfram Research for MathWorld and the Wolfram Functions site.
  These are the main references used for special functions
  implementations.
* George Brandl for developing the Sphinx documentation tool
  used to build mpmath's documentation

1. Download & installation
--------------------------

Mpmath requires Python 3.8 or later versions. It has been tested
with CPython 3.8 through 3.12 and for PyPy.

The latest release of mpmath can be downloaded from the mpmath
website and from https://github.com/mpmath/mpmath/releases

It should also be available in the Python Package Index at
https://pypi.python.org/pypi/mpmath

To install latest release of Mpmath with pip, simply run

``pip install mpmath``

or from the source tree

``pip install .``

The latest development code is available from
https://github.com/mpmath/mpmath

See the main documentation for more detailed instructions.

2. Documentation
----------------

Documentation in reStructuredText format is available in the
docs directory included with the source package. These files
are human-readable, but can be compiled to prettier HTML using
`Sphinx <https://www.sphinx-doc.org/>`_.

The most recent documentation is also available in HTML format:

https://mpmath.org/doc/current/

3. Running tests
----------------

The unit tests in mpmath/tests/ can be run with `pytest
<https://pytest.org/>`_, see the main documentation.

You may also want to check out the demo scripts in the demo
directory.

The master branch is automatically tested on the Github Actions.

4. Known problems
-----------------

Mpmath is a work in progress. Major issues include:

* Some functions may return incorrect values when given extremely
  large arguments or arguments very close to singularities.

* Directed rounding works for arithmetic operations. It is implemented
  heuristically for other operations, and their results may be off by one
  or two units in the last place (even if otherwise accurate).

* Some IEEE 754 features are not available. Inifinities and NaN are
  partially supported; denormal rounding is currently not available
  at all.

* The interface for switching precision and rounding is not finalized.
  The current method is not threadsafe.
