What is a decimal number?

It is a number with or without a decimal point. It is the most widely used form in our world. It allows arithmetic operations. The numbers are base 10 and made up of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

What is a binary number?

It is a numbering system using base 2. It is used in electronics and computing. Since a computer is a machine (made of electronic components), it only understands binary language and stores information in a bit that can only take two values. Binary numbers are made up of 0s and 1s.

What is a hexadecimal number?

The hexadecimal system is made up of 16 basic values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F. It is therefore a numbering system using base 16. This system is used in computing and makes it possible, among other things, to compress binary code. For example, color codes are often written in hexadecimal (blue = 0002ff).
