"WebStage 1: Floating Point Ranges At a very broad level arithmetic coding works by taking a character and assigning it a frequency to a table. This frequency is then mapped to a number line between 0 and 1. So, if we have the character frequency table as shown below for the word “HELLO”, we would end up with our number line shown below.
