Oct to Dec

Octal

• Definition: Octal is a base-8 numeral system that uses digits from 0 to 7. It is one of the positional numeral systems and is frequently used in computing and digital systems.

• Symbol: The octal system is usually denoted by a subscript 8, for example, 17₈.

• Usage: Octal is often used in computer programming and digital electronics, as it can represent binary numbers in a more compact form. Each octal digit corresponds to three binary digits.

Decimal

• Definition: Decimal is a base-10 numeral system that employs digits from 0 to 9. It is the most commonly used number system in everyday life.

• Symbol: The decimal system is typically represented without any special notation, but it can be denoted by a subscript 10, such as 17₁₀.

• Usage: The decimal system is used in most aspects of daily life, including money, measurements, and calculations.

Origin of the octal

• The octal system traces its roots back to ancient civilizations that used base-8 counting methods. Its practical application became more prominent with the development of computing, as it simplifies the representation of binary data.

Origin of the decimal

• The decimal system originated from the human tendency to count using ten fingers. It has been in use for thousands of years and has evolved into the standard numerical system used in commerce, science, and daily life.
