Detailed explanation

Hexadecimal(abbreviated as hex or subscript 16) is a number system with base 16, a carry system that increments by 1 at 16. It is usually represented by the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and the letters A, B, C, D, E, F (a, b, c, d, e, f), where A~F represent 10~15, and these are called hexadecimal digits.

Decimal numberis a number system based on 10, composed of ten basic digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Decimal, with the English name Decimal System, comes from the Greek word Decem, meaning ten. Decimal counting was invented by Hindus 1,500 years ago and was passed down by Arabs to the 11th century.

Octal, Octal, abbreviated OCT or O, is a counting method with base 8, using the eight digits 0, 1, 2, 3, 4, 5, 6, 7, and increments by 1 at 8. In some programming languages, a number starting with the digit 0 often indicates that it is octal. Octal numbers and binary numbers can correspond bit by bit (one octal digit corresponds to three binary digits), so it is often used in computer languages.

Binaryis a number system widely used in computing technology. Binary data uses0and1two digits to represent numbers. Its base is 2, the carry rule is "add one when reaching two", and the borrow rule is "borrow one as two". Binary numbers (binaries) are a carry system that increments at 2; 0 and 1 are the basic operators; computers use binary as the basis of computation.
