- 1十六進位（中國大陸多寫「十六进制」）
Hexadecimal numbers are a way of counting that uses sixteen as the base, not ten. You still have 0 to 9, and then the letters A, B, C, D, E, F stand for ten through fifteen. Computers like this system because sixteen fits onto the on/off bits inside the machine; that is why colour codes on the web look like #FF0000, and why programmers often show memory in hex. People it to hex in tech talk. Though actually, the name tricks : hexa- means six, and decimal means ten, and six plus ten is sixteen — it is not a six-based system. The word was built in 1952 for computing. It has nothing to do with a witch’s hex.
組成hexa- (six) + decimal (ten). Six and ten make sixteen, so the system uses sixteen symbols (0–9 and A–F). Coined in 1952. Not related to the curse word hex.
