octal

Octal is a numeral system for representing a numeric value as base 8. Generally, an octal digit is represented as "0" to "7" with the same value as for decimal but with each place a power of 8. For example: \mathbf{112}_8 = \mathbf{1} \times 8^2 + \mathbf{1} \times 8^1 + \mathbf{2} \times 8^0

In decimal, each place is a power of ten. For example: \mathbf{74}_{10} = \mathbf{7} \times 10^1 + \mathbf{4} \times 10^0
