Base36 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-36 (aka Hexatrigesimal) representation. The choice of 36 is convenient in that the digits can be represented using the Arabic numerals 0–9 and the Latin letters A–Z (the ISO basic Latin alphabet).
| hexatrigesimal (base 36) | 136 | 236 | 336 | 436 | 536 | 636 | 736 | 836 | 936 | a36 |
| binary (base 2) | 12 | 102 | 112 | 1002 | 1012 | 1102 | 1112 | 10002 | 10012 | 10102 |
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.
