An encoding of all binary strings in the range to all [Binary] strings in the domain, based on an expected probability distribution of bitstings. The encoder starts with the range [0,1) and to encode reach bit the encoder takes the expected distribution of the bit (maybe 20/80) and divides the range in those proportions and throws away the portion the bit didn't fall into (in this case either [[0,0.2) or [[0.8,1) ). When all bits have been seen the range is sent as the encoding. |

ArithmeticDecoding is the reverse process. |

ArithmeticEncoding has been shown to be the asymototical optimal way to encode such a string (only asymototical optimal because of the need to round up the range to the nearest bit). |

ArithmeticEncoding and ArithmeticDecoding are used in bzip2(1) and but zip(1). |
