HEX – for websites and coding HEX, or hexadecimal numbers, is a human-friendly way to communicate color to computers. There is no informational difference between RGB and HEX colors; they are simply different ways of communicating the same thing – a red, green, and blue color value.

The reason for hex is that it is so much more intuitive and practical to use. It is quicker to write, because it requires fewer characters. With bits, you would be very likely to miss count at some point and also wouldn’t notice typos, because who actually remembers all 24 characters.

Hexadecimal (or hex) is a base 16 system used to simplify how binary is represented. This means an 8-bit binary number can be written using only two different hex digits – one hex digit for each nibble (or group of 4-bits). It is much easier to write numbers as hex than to write them as binary numbers.

Hexadecimal describes a base-16 number system. That is, it describes a numbering system containing 16 sequential numbers as base units (including 0) before adding a new position for the next number. Two hexadecimal digits can represent eight binary digits, or a byte.

The value of HEX FF in decimal is 255. The value of HEX FF in binary is 11111111. F. 15 X 16.

Likewise, to count higher than FF we would add a third hexadecimal digit to the left so the first 3-bit hexadecimal number would be 10016, (25610) and the last would be FFF16, (409510).

To denote a hex literal in C 0x was adopted as the prefix and carried on to its successors. 0xFF = 15*16+15 = 255. Since FF(hex) = 255(dec), it follows that 0xFF = 00FF if leading zeroes are not suppressed. Therefore x stands for 0.

Hex 3AF to Binary Conversion

0x100 = 256 You almost had it right with math calculating 256. It’s the number of distinct values you can have with the 2 digits in hex. – 0 … 255 are 256 numbers.

My book says the hexadecimal notation FFFF equals 65535 in decimal value.

0xff is a number represented in the hexadecimal numeral system (base 16). It’s composed of two F numbers in hex. As we know, F in hex is equivalent to 1111 in the binary numeral system. So, 0xff in binary is 11111111.
