Below, we'll walk you through the swap step by step and show you how to use the tool so you get fast, correct results every time.
What is Decimal to Octal?
- Decimal and Octal, both are the way to write numbers.
- (Decimal Base-10 from Zero to Nine) But we use it for nearly everything else in our daily lives.
- Octal (Base-8) numeric representation is 0 to 7 only. The reason programmers love it is that it takes the long binary data and packs them into small, easy sizes.
How to Change a Decimal Number Into Octal
Turning a decimal number into octal is simple—you keep dividing by 8 and jotting down the leftovers. Follow these quick steps:
- Divide the decimal by 8 and note the remainder.
- Take the new quotient, divide by 8 again, and write down the next remainder.
- Keep going until the quotient hits zero, then read all the remainders backward.
For example, to convert the decimal number 34 to octal:
-
34 ÷ 8 = 4, remainder 2
-
4 ÷ 8 = 0, remainder 4
-
The octal representation of 34 is 42 (read the remainders from bottom to top).
Quick Formula for Decimal to Octal
