Extended data:

Since one number in hexadecimal can correspond to four binary numbers, it is more convenient to represent binary numbers in hexadecimal. Therefore, octal application is not as good as hexadecimal. Some programming languages provide the ability to use octal symbols to represent numbers, but there are still some older Unix applications that use octal symbols.

The computer needs to convert the number system. The computer uses the number system conversion between binary and binary octal decimal, which is compiled by FORTRAN77. The number system conversion between binary octal decimal is completed around binary and decimal.
