0o223

0o223 refers to a number represented in octal notation. The prefix "0o" is a common way to denote an octal number, and "223" are the digits used in this base-8 system. In octal, each digit represents a power of 8, starting from the rightmost digit as 8^0, then 8^1, 8^2, and so on.

To convert 0o223 to its decimal (base-10) equivalent, we can expand it as follows: (2 * 8^2) + (2 * 8^1) + (3 * 8^0). This calculation results in (2 * 64) + (2 * 8) + (3 * 1), which equals 128 + 16 + 3. Therefore, 0o223 in octal is equivalent to 147 in decimal.

Octal notation is a base-8 numeral system and was historically used in some computing contexts, particularly with older mainframe systems and minicomputers. It is less common today than decimal or hexadecimal, but it can still be encountered in specific programming environments or in discussions about legacy systems. Its advantage lies in its direct relationship to binary (base-2) representation; three octal digits can represent exactly one 12-bit binary number, or conversely, one octal digit corresponds to exactly three binary digits.
