WebIn mathematics and computer science, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a–f) to represent values ten to fifteen. WebTo me, the "hexadecimal value" is a numeric type where the byte 6f is actually stored on the machine as binary 0110 1111 (which is 6f). In many languages, C++ included, you can achieve this by prepending "0x" to the value: unsigned int some_hex = 0x6f;
