0o4672

0o4672 is an octal integer literal used in several programming languages to denote a number in base 8. The prefix 0o signals octal notation. The value of 0o4672 in decimal is 2490; in hexadecimal it is 0x9ba, and in binary it is 100110111010.

Octal notation is commonly encountered in contexts involving permissions and bit masks. In Unix-like systems, file modes can be expressed in octal. The leading digit in a four-digit octal mode captures special bits (such as set-user-ID), while the remaining three digits control owner, group, and others permissions. For 0o4672, the leading 4 indicates the set-user-ID bit is set. The permissions digits 6, 7, and 2 correspond to owner rw-, group rwx, and others -w-, respectively. Therefore, 0o4672 represents a mode with the setuid bit set and the specified owner/group/other permissions.

In Python 3 and many other languages, 0o4672 can appear as a literal value. It is a convenient way to work with octal-based masks or constants that reflect permissions or bit fields. Converting between bases is straightforward: the decimal value is 2490, the hexadecimal representation is 0x9ba, and the binary representation is 100110111010. When writing code that handles file modes or low-level bit operations, using the 0o prefix helps make the octal nature of the value explicit.
