0o360

0o360 is an octal numeric literal used in several programming languages to denote the integer value represented by the octal digits 3, 6, and 0. In base 8, the value is calculated as 3×8^2 + 6×8^1 + 0×8^0, which equals 240 in decimal. This same value corresponds to 0xF0 in hexadecimal and 11110000 in binary.

The 0o prefix is used in languages such as Python 3 and modern JavaScript (ES6 and later) to clearly indicate octal notation, distinguishing it from decimal literals and hexadecimal literals (0x...). Historically, octal literals were sometimes written with a leading zero alone (for example, 0360 in C or C++), which could be confusing and error-prone if digits outside 0–7 were used.

In practice, 0o360 is simply a way to express the number 240 in code. When a program uses this literal, operations such as addition, subtraction, and bitwise operations treat it as the integer value 240. As with other octal literals, values containing digits 8 or 9 are invalid in octal notation and will cause a parsing error in languages that enforce base-8 digits.

Usage is language-specific; some environments may require strict adherence to the octal prefix, while others parse older octal forms differently. Overall, 0o360 serves as a concrete example of octal notation and its decimal/hex equivalents.
