Release history:
Mpmath requires Python 2.5 or later. It has been tested with Python 2.5, 2.6, 2.7, 3.1 and 3.2.
The latest release of mpmath can be downloaded from the mpmath website. It should also be available in the Python Package Index at http://pypi.python.org/pypi
To install, unpack the mpmath archive and run
python setup.py install
Mpmath can also be installed using
python -m easy_install mpmath
The latest development code is available from http://code.google.com/p/mpmath/source/checkout
See the main documentation for more detailed instructions.
The unit tests in mpmath/tests/ can be run via the script runtests.py, but it is recommended to run them with py.test (http://codespeak.net/py/dist/index.html), especially to generate more useful reports in case there are failures.
You may also want to check out the demo scripts in the demo directory.
Documentation in reStructuredText format is available in the doc directory included with the source package. These files are human-readable, but can be compiled to prettier HTML using the build.py script (requires Sphinx, http://sphinx.pocoo.org/).
See setup.txt in the documentation for more information.
The most recent documentation is also available in HTML format on the mpmath website:

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.
