In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system or base-2 numeral system which represents numeric values using two different symbols: typically 0 (zero) and 1 (one). The base-2 system is a positional notation with a radix of 2. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by almost all modern computers and computer-based devices. Each digit is referred to as a bit.
| binary (base 2) | hexadecimal (base 16) | binary (base 2) | hexadecimal (base 16) |
|---|---|---|---|
| 1 | = 1 | 1011 | = b |
| 10 | = 2 | 1100 | = c |
| 11 | = 3 | 1101 | = d |
| 100 | = 4 | 1110 | = e |
| 101 | = 5 | 1111 | = f |
| 110 | = 6 | 10000 | = 10 |
| 111 | = 7 | 10001 | = 11 |
| 1000 | = 8 | 10010 | = 12 |
| 1001 | = 9 | 10011 | = 13 |
| 1010 | = a | 10100 | = 14 |
In mathematics and computing, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a, b, c, d, e, f) to represent values ten to fifteen.
| hexadecimal (base 16) | binary (base 2) | hexadecimal (base 16) | binary (base 2) |
|---|---|---|---|
| 1 | ≈ 1 | b | ≈ 1011 |
| 2 | ≈ 10 | c | ≈ 1100 |
| 3 | ≈ 11 | d | ≈ 1101 |
| 4 | ≈ 100 | e | ≈ 1110 |
| 5 | ≈ 101 | f | ≈ 1111 |
| 6 | ≈ 110 | 10 | ≈ 10000 |
| 7 | ≈ 111 | 11 | ≈ 10001 |
| 8 | ≈ 1000 | 12 | ≈ 10010 |
| 9 | ≈ 1001 | 13 | ≈ 10011 |
| a | ≈ 1010 | 14 | ≈ 10100 |
