โ“ Frequently Asked Questions

What is the difference between Octal and Binary?

Octal (OCT) and Binary (BIN) are positional numeral systems with different radix bases. In computer architecture, values are converted between bases using arbitrary-precision binary/hex representations.

How do I convert Octal to Binary?

Parse each digit of the Octal input according to its base powers, then repeatedly divide or format the integer into the target Binary radix digits.
