pwagen Posted February 19, 2013 Share Posted February 19, 2013 Well, with 1 bit, you can represent 0 and 1. With 2 bit, you can represent 0-3. The formula should be something like 2^n-1, where n is the number of bits needed. So you either do that calculation, or you do it manually by increasing the number of bits you have until you can represent the number you want.
