In mathematics and computer science, hexadecimal (also base Template:Num, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0â9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively aâf) to represent values ten to fifteen. For example, the hexadecimal number 2AF3 is equal, in decimal, to (2 Ã 163) + (10 Ã 162) + (15 Ã 161) + (3 Ã 160) , or 10,995.
