What is the reason why psp has such a relationship with 255? Is it because the eighth power of 2-1 is the largest short integer data that a computer can handle?
The numbers 0-255-* * 256 are actually the largest of these numbers, and 255 is the eighth power of 2.
Psp is the same as computer in many aspects, so some data are the same as computer. If you look at it with a golden finger, it is 255, which is the reason. The maximum value is 255, but you can switch to the decimal system and change it larger.
