octal value

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

Basic knowledge Decimal The base number is 10, and every 10 goes into 1. In decimal format, a total of 10 different numeric symbols are used. When these symbols are in different positions, their weights are different. Binary The base number is 2,

Ii. Convert hexadecimal to decimalConvert binary to decimal: 0th bits in binary are 0 to the power of 2, and 1st bits are 1 to the power of 2 ......Therefore, there is a binary number: 0110 0100, which is converted to a 10-digit system:The following
