0o340

0o340 is an octal numeral representation that corresponds to the decimal number 224. In the octal system, which uses base 8, the prefix "0o" indicates that the following digits are to be interpreted in octal notation. Each digit in an octal number represents a power of 8, with the rightmost digit being 8^0, the next to the left being 8^1, and so on. Breaking down 0o340, we have 3 × 8² (192) + 4 × 8¹ (32) + 0 × 8⁰ (0), which sums to 224 in decimal. Octal numbers were commonly used in early computing systems because they provide a more compact representation of binary values, with each octal digit corresponding to exactly three binary digits. Today, octal notation is less frequently used in favor of hexadecimal, but it still appears in certain programming contexts and Unix file permissions.
