Numbering SystemsAPPENDIX B
Numbering SystemsWe use different numbering systems: base 10 (decimal), base 2 (binary), base 8 (octal), base 16 (hexadecimal), base 256, and so on. All the numbering systems examined here are positional, meaning that the position of a symbol in relation to other symbols determines its value. Each symbol in a number has a position. The position traditionally starts from 0 and goes to n − 1, where n is the number of symbols. For example, in Figure B.1, the decimal number 14,782 has five symbols in positions 0 to 4.
