**What is a hexadecimal number?**

Hexadecimal number is an abbreviation for hexadecimal number, which is a number represented in the hexadecimal positional number system with base 16, using 16 symbols: the numbers 0 through 9 and the letters A, B, C, D, E, and F , to represent values between 0 and 15. Similarly, the lowercase letters a through f may be used.For example, 10 in decimal is hexadecimal A, 100 in decimal is hexadecimal 64, and 1,000 in decimal is hexadecimal 3E8.Hexadecimal numbers have symbols, just like decimal numbers, e.g., -1e in decimal equals -30.

Hexadecimal numbers are primarily used in computing: computer system designers, software engineers, and programmers as a convenient representation of the underlying binary system. People in such occupations are most likely to need a hexadecimal calculator or hexadecimal converter.

The average person encounters them every day when browsing the Web, as special characters in Web site addresses (URLs) are encoded as hexadecimal numbers, such as %20 for "space" (blank).
