Your original comment does not show that you are one of the few able to just read and understand a simple algorithm. Look around the many comments here where people misread this simple algorithm and readily jumps to premature conclusions. I

This way you can get the 9 evenly spaced aproximate numbers 1.28 = 128/100 1.6 = 16/10 2 2.56 = 256/100 3.2 = 32/10 4 5.12 = 512/100 6.4 = 64/10 8 Do you have any more tricks? Edit: Searc
