0o540

0o540 is a numerical value represented in octal (base-8) notation. In decimal (base-10) notation, it is equivalent to 352. Octal is a base-8 number system, using digits 0-7. The prefix "0o" is used in some programming languages to denote octal numbers, although this convention is not universally adopted. In octal, each digit represents a power of 8, starting from the rightmost digit which represents 8^0. For example, in 0o540, the digit 0 represents 0*8^0, the digit 4 represents 4*8^1, and the digit 5 represents 5*8^2. When converted to decimal, the value is calculated as (5*8^2) + (4*8^1) + (0*8^0) = 320 + 32 + 0 = 352. Octal notation is often used in computing and digital electronics due to its direct correspondence with binary (base-2) systems, which is the foundation of digital data representation.
