Essential for the test: binary, decimal, hexadecimal, and octal Conversion

conversion The conversion between the hexadecimal and binary systems is very simple. The hexadecimal to binary system processes every bit of the hexadecimal system as a binary four-bit system. If there are less than four digits, add a zero complement. If binary is converted to hexadecimal, the four bits of binary are processed as one of the hexadecimal values. See the example below: 1) convert the hexadecimal number 0209fe83 to 1000001001111111101000 binary 0 0000 2 0010 0 0000 9 1001 F 1111 E

The following methods are summarized here. The default value of a shell script is a 10-digit number, which can represent other numeric values unless the number starts with a special markup method or prefix.
