0o7442

0o7442 is a numeric literal written with an octal prefix, used in languages that adopt the 0o convention for octal notation (notably Python 3 and several other modern languages). The digits 7, 4, 4, and 2 specify the value in base-8.

In decimal, 0o7442 equals 3874, calculated as 7×8^3 + 4×8^2 + 4×8^1 + 2×8^0. In hexadecimal, this value is 0xF22, and in binary it is 111100100010.

If interpreted as a Unix-style file mode, 0o7442 corresponds to a four-digit octal permission where the leftmost digit (7) represents all three special bits (setuid, setgid, and sticky), and the remaining digits (4, 4, 2) map to user, group, and other permissions respectively. In this interpretation, the permissions would be: user read, group read, others write, with all three special bits set. How such a mode behaves depends on the operating system and context.

As a general programming value, 0o7442 is simply an octal literal whose meaning depends on the surrounding code and the language's interpretation of the value. It does not denote a widely recognized standard identifier by itself.
