Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble). Software developers and system designers widely use hexadecimal numbers because they provide a human-friendly representation of binary-coded values. Unlike the decimal system representing numbers using 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" (or alternatively "a"–"f") to represent values from 10 to 15. In mathematics and computing, the hexadecimal (also base-16 or simply hex) numeral system is a positional numeral system that represents numbers using a radix (base) of 16.
