If you move it to the left the number would increase so for example you had 2.3 and you move it to the left then it would be 23, so if you times it by tenth or hundredth then it would go to the left but if you divide then it would go down so moving to the right would get you 0.23
A reasonable way to use them is to code the five most-common strings in the ... bytes, compared to a bitmap size of only 6 × 8 bits = 6 bytes. ... Columns 2, 4, 5, and 7 yield the six runs 0,5,1,1,1,eol each. ... 2.3: Replacing 10 by 3 we get x = k log2 3 ≈ 1.58k. ... Table Ans.3: Probabilities and Entropies of Two Symbols.
