0667

0667 is a four-digit numeric string that can denote different things depending on the context. When treated as a decimal integer, it is equal to 667. The leading zero is typically a formatting choice rather than part of the numeric value.

In computing, some programming languages interpret a leading zero as indicating octal notation. In such cases, 0667 is an octal literal; its value in decimal is 439. Many modern languages require an explicit syntax to denote octal, such as 0o667 in Python or a different notation in other languages.

Outside number theory and programming, 0667 commonly appears as an identifier in cataloging systems. It may serve as part of serial numbers, product models, inventory codes, or data records that use padded numeric fields. In these contexts, the sequence itself carries no intrinsic mathematical meaning beyond being a label.

As with other numeric strings, the precise interpretation of 0667 depends on the system in which it is used. See also 667 and the octal numeral system.
