* int to binary

  .. code-block:: python

    >>> bin(6)
    '0b110'
    >>> bin(6)[2:]
    '110'


* binary to int

  .. code-block:: python

    >>> int('11111111', 2)
    255

    >>> from bitstring import BitArray
    >>> b = Bitarray(bin='11111111')
    >>> b.uint
    255
    >>> b.int
    -1
