IN MATH: 1. adj. base 16. Instead of 10 digits -- 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 -- the notation uses 16 digits -- 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. See above. Ex. Web page color is named in words or written as a sequence of three hexadecimal numbers indicating the quantities of red, green, and blue in the color.

    Using 16 digits rather than only 10 digits permits one to write most numbers using fewer digits. For example, the number two thousand, eight hundred forty-seven is written as 2847 in decimal notation and as B1F in hexadecimal notation. The number five million, four hundred sixty-two thousand, eight hundred forty-seven is 5,462,847 as a decimal and 535B3F as a hexadecimal.

    Change base 10 number to base 16 number.
