Non Decimal Numbers

The number of digits a numeric system uses is called its radix. The radix of a number is often displayed as a subscript at the end of the number. For example For raw data, programmers use numbers that are base 2 (binary), base 8 (octal), or base 16 (hexadecimal or just “hex”). All these number systems are convenient for working with raw data because they are powers of two. When using base 2, there are 2 digits (0 and 1) and each digit represents a power of 2. When using base 8, there are 8 digits (0, 1, 2, 3, 4, 5, 6, 7) and each digit represents a power of 8. When using base 16 there are 16 digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F) and each digit represents a power of 16. Hex numbers are most programmers favorite because each digit corresponds to four bits:

The table below shows the equivalent decimal, hex, octal and binary numbers from 0 to 32 (decimal).
