hexadecimal
Sign in to saveHexadecimal (hex for short) is a positional numeral system for representing a numeric value as base 16. For the most common convention, a digit is represented as "0" to "9" like for decimal and as a letter of the alphabet from "A" to "F" (either upper or lower case) for the digits with decimal value 10 to 15.
AI overview
Hexadecimal is a counting system that uses 16 different symbols—the numbers 0-9 and the letters A-F—instead of the 10 digits we normally use in everyday math. It's commonly used in computing because it provides a compact and convenient way to represent numbers that computers work with internally.

As typical computer hardware is binary in nature and that hex is power of 2, the hex representation is often used in computing as a dense representation of binary information. A hex digit represents 4 contiguous bits known as a nibble. An 8-bit byte is two hex digits, such as .
