decimal to octal Algorithm
Positional notation (or place-value notation, or positional numeral system) denotes normally the extension to any base of the Hindu – In modern positional systems, such as the decimal system, the position of the digit means that its value must be multiply by some value: in 555, the three identical symbols represent five hundreds, five tens, and five units, respectively, due to their different positions in the digit string. Some of those pro-decimal attempts — such as decimal time and the decimal calendar — were unsuccessful. count rods and most abacuses have been used to represent numbers in a positional numeral system. Before positional notation became standard, simple additive systems (sign-value notation) such as Roman numerals were used, and accountants in ancient Rome and during the center age used the abacus or stone counters to do arithmetical.
