Arithmetic coding
The arithmetic coding is a technique of compression without loss. Normally a chain of cartactères like " hello world" is representable by using a fixed number of Bit S by character, as in the code ASCII. Like the Coding of Huffman, arithmetic coding is a code with variable length. What differentiates arithmetic coding from the others codings source is that it encode the message entirely and represents it by only one number (floating) whereas other codings separate the message from entry in the symbols which compose it and encodent then each symbol by a word codes.
