What's Octal Decimal System?
Definition: The number system whose base is 8 is known as the octal number system. All the eight digits from 0 to 8 have same physical meaning as that of decimal numbers. The next digit in octal number is represented by 10, 11, 12, 13, 14, 15, 16, 17,18 which represents the decimal digits 8, 9, 10, 11, 12, 13, 14, 15,16 .
Method for Octal to Decimal Conversion :
Converting octal to decimal can be done with repeated division.
Start the decimal result at 0.
Remove the most significant octal digit (leftmost) and add it to the result.
If all octal digits have been removed, you’re done. Stop.
Otherwise, multiply the result by 8.
Go to step2.
The conversion can also be performed in the conventional mathematical way, by showing each digit place as an increasing power of 8.
144 octal = (1 * 8^2) + (4 * 8^1) + (1 * 8^0) = (1 * 64) + (4 * 8) + (4 * 1) = 100 decimal
What is the first step in converting an octal number to decimal?
How to Convert Octal to Decimal?
Octal Number System:
The octal numeral system, or oct for short, is the base-8 number system, and uses the digits 0 to 7. Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three (starting from the right).
2:
The decimal numeral system (also called base-ten and occasionally called denary) has ten as its base, which, in decimal, is written 10, as is the base in every positional numeral system. It is the numerical base most widely used by modern civilizations.
Example 1 : Input = 144
Output = 100
Example 2 : Input = 100
Output = 64
Example 2 : Input = 101
Output = 65
