For example, using the hex number AAA:ĪAA = 10 × 16 2 + 10 × 16 1 + 10 × 16 0 = 2560 + 160 + 10 = 2730Īs can be seen, although the symbols occupying the three positions shown are the same, "A," the magnitude of each is one power of 16 apart. Being a positional numeral system means that each position represents a different magnitude.
Definition: The hexadecimal numeral system is a base-16 positional numeral system that uses the same symbols as the decimal system to represent the values of zero to nine (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and the letters A, B, C, D, E, and F to represent the values of ten to fifteen.
