Why do we need octal and hexadecimal?
In programming, we usually use 10 hexadecimal notation ...... C/C ++ is a high-level language.
For example:
Int A = 100, B = 99;
However, because the representation of data in a computer exists in
In programming, we usually use 10 hexadecimal notation ...... C/C ++ is a high-level language.
For example:
Int A = 100, B = 99;
However, because the representation of data in a computer exists in binary format, sometimes binary can be used to solve
Binary data is a position-counting method with a power of 2 at the bottom, every 2 into 1.
1. Binary and Decimal Interchange: (1) Binary decimal method: "Expand by Weight" example: (1011.01) 2 = (1x2^3+0x2^2+1x2^1+1x2^0+0x2^ ( -1) +1x2^ (-2)) 10 = (8
