Octal

 Octal system

What is it:

Octal system. The number system in base 8 is called octal and uses the digits 0 to 7. Octal numbers can be constructed from binary numbers by grouping every three consecutive digits of the latter (from right to left) and obtaining their decimal value.

How to tell:

The largest octal digit is 7; in this way, when counting in this system, a digit position is increased from 0 to 7. When 7 is reached, it is recycled to 0 for the next count; in this way the next digit position is increased. For example, to count sequences, in the octal system it will be:

• 0, 1, 2, 3, 4, 5, 6, 7, 10.

• 53, 54, 55, 56, 57, 60.

• 375, 376, 377, 400.
