        "description": "PiDigits\n********\n\n*PiDigits* Implements the 'Unbounded Spigot Algorithm for the Digits of Pi' by\nJeremy Gibbons. The paper describing this algorithm can be found at this\n`URL`_. The same algorithm is used to generate digits of `Tau`_. No matter which\ncircle constant you prefer, you can now generate the decimal expansion using\nthis package.\n\nInstallation\n------------\n*pidigits* is avalaible through Python Package Index (`PyPI`_) using `pip`_. ::\n\n   >>> pip install --upgrade pidigits\n\nTo uninstall using `pip`_. ::\n\n   >>> pip uninstall pidigits\n\nUsage\n-----\nPiDigits provides a generator function named *piGenerator* that yields the\ndigits of Pi as needed. The streaming algorithm based on Lambert's expression\nis used for the generator function. ::\n\n    >>> from pidigits import piGenerator\n    >>> mypi = piGenerator()\n    >>> first20pi = [next(mypi) for i in range(20)]\n    >>> first20pi\n    [3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5, 8, 9, 7, 9, 3, 2, 3, 8, 4]\n\n**Example**: Verify the `Feynman point`_. ::\n\n    >>> mypi = piGenerator()\n    >>> first1001 = [next(mypi) for i in range(1001)]\n    >>> feynman = first1001[762:768]\n    >>> print feynman\n    [9, 9, 9, 9, 9, 9]\n\nAlternatively you can also use the *getPi(n)* function to get the first *n*\ndigits of Pi. ::\n\n    >>> from pidigits import getPi\n    >>> first20pi = getPi(20)\n    >>> first20pi\n    [3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5, 8, 9, 7, 9, 3, 2, 3, 8, 4]\n\nAlternate implementations of streaming algorithms based on Leibniz series and\nGosper's series are also available as generator functions *piGenLeibniz* and\n*piGenGosper* and corresponding *getPiLeibniz* and *getPiGosper* functions.\nThese implementations are slower than the one based on Lambert's series.\n\nPidigits also provides a generator function name *tauGenerator* that yields the\ndigits of `Tau`_ as needed. ::\n\n    >>> from pidigits import tauGenerator\n    >>> mytau = tauGenerator()\n    >>> first20tau = [next(mytau) for i in range(20)]\n    >>> first20tau\n    [6, 2, 8, 3, 1, 8, 5, 3, 0, 7, 1, 7, 9, 5, 8, 6, 4, 7, 6, 9]\n\nAlternatively you can also use the *getTau(n)* function to get the first *n*\ndigits of Tau.\n\nDevelopment\n-----------\nIf you clone the repository (`GitHub`_, `BitBucket`_) and make any changes to\nthe algorithm you can run the test cases in the _tests package included with\nthe source to test your changes.\n\nTo run the tests, in the same directory as *setup.py*, first run: ::\n\n    >>> python setup.py develop\n\nThis will install the package in the 'development' mode. Then run the\ntest cases: ::\n\n    >>> python setup.py test\n\n`Bug reports`_ or suggestions are most welcome.\n\nLicense\n-------\npidigits is licensed under `Apache License 2.0`_.\n\n.. _URL: http://www.cs.ox.ac.uk/jeremy.gibbons/publications/spigot.pdf\n.. _PyPI: https://pypi.python.org/pypi\n.. _pip: https://pip.pypa.io\n.. _Apache License 2.0: https://www.apache.org/licenses/LICENSE-2.0.html\n.. _Feynman point: http://en.wikipedia.org/wiki/Feynman_point\n.. _GitHub: https://github.com/transmogrifier/pidigits\n.. _BitBucket: https://bitbucket.org/transmogrifier/pidigits\n.. _Bug reports: https://github.com/transmogrifier/pidigits/issues\n.. _Tau: https://tauday.com/tau-manifesto",
