factorial(n)

..  factorial(n)

Factorial of ``n``.  If ``n`` is an :obj:`Integer`, the factorial
is computed as an integer (promoted to at least 64 bits).  Note
that this may overflow if ``n`` is not small, but you can use
``factorial(big(n))`` to compute the result exactly in arbitrary
precision.  If ``n`` is not an ``Integer``, ``factorial(n)`` is
equivalent to :func:`gamma(n+1) <gamma>`.
