To reduce the size of the grid on the screen and to facilitate entering values, the possibilities are represented here by the following hexadecimal digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F. The hexadecimal system is a numeral system with a base of 16, using Arabic numerals to represent values 09 and the letters AF for the other six. The hexadecimal is especially useful in computer science because it is much easier to map binary to hexadecimal than to decimal.
