Question: Question:
Is 2's complement used in the computer? 1's complement may be used, and if it can be checked, how should I check it? [Addition]
If 1's complement is used if it depends on the implementation, why?
If it's 2's complement, you can see the advantage.
Answer: Answer:
Most (or rather all) modern CPUs use two's complement systems.
Oiler has experience with a type of CPU that isn't enough with both hands,
All of them adopted the two's complement system.
(H8 / H8S / H8SX / RX / 8080 / Z80 / 8086/80186/80286/x86/x64/68000/V850/MN101/MN103/RL/78K/78K0R)
As of the 21st century, it is safe to assume that you will never use a CPU that is not two's complement.
He is a one's complement, and if he ever uses a CPU, he should be lucky to have valuable experience.
You understand the benefits of using 2's complement system.
