Hexadecimal (also base 16, or hex) is a positional numeral system with a base of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A–F (or alternatively a–f) (the first 6 letters of the English alphabet) to represent values ten to fifteen. Hexadecimal numerals are widely used by computer system designers and programmers, as they provide a more human-friendly representation of binary-coded values. Each hexadecimal digit represents four binary digits, also known as a nibble, which is half a byte. For example, a single byte can have values ranging from 0000 0000 to 1111 1111 in binary form, which can be more conveniently represented as 00 to FF in hexadecimal.
The use of the letters A through F to represent the digits above 9 was not universal in the early history of computers. There are also no signs that numeral systems of base 16 were used in the past.
