Octal number system is a base-8 number system where the range of numbers is 0,1,2,3,4,5,6,7. Binary numbers can be grouped into a pair of three to get octal numbers. Learn conversion with examples at BYJU’S.
Number system with base 8 and symbols ranging between 0-7 is known as the Octal Number System. Each digit of an octal number represents a power of 8. It is widely used in computer programming and digital systems.
A number system with base 8 is called an octal number system. The position of every digit has a value which is a power of 8. A number in the octal number system is represented with the number 8 at the base, like $512_8,\; 56_8$ , etc.
A number system with its base as eight and uses numbers from 0 to 7 is called Octal Number System. The symbol of the octal is used to represent the numbers that have eight as the base. Learn about definition of octal number system, conversion to binary, decimal and hexadecimal number systems.
In the octal system, each place is a power of eight. For example: By performing the calculation above in the familiar decimal system, we see why 112 in octal is equal to in decimal.
The octal number system is the base 8 number system. Thus, it has 8 characters or numbers starting from 0 to 8. It is written as 214 8. Some more examples of octal numbers are 558, 1018, 608. In 1801, James Anderson suggested the base 8 number system and coined the term ‘octal.’.
Octal Number System. In the hexa decimal number system, we represent the binary digits as a set of 4 digits (2 4 = 16), in octal numbering system we represent the binary numbers as a set of 3 digits (2 3 = 8). The octal number system uses 8 numbers from 0 – 7. They are 0, 1, 2, 3, 4, 5, 6 and 7.

Octal is a number system with a base of 8 i.e. it uses 8 numeric values, namely, {0, 1, 2, 3, 4, 5, 6, 7}. This number system is mostly used in the programming of computer programs. For example (32150.7642)8, (275)8, (324)8, (2243)8 are Octal numbers. In this article, we will discuss the octal number system.
Definition: The number system whose base is 8 is known as the octal number system. The base 8 means the system uses eight digits from 0 to 7. All the eight digits from 0 to 8 have same physical meaning as that of decimal numbers.
