0017

0017 is the four-digit decimal notation for the number 17 with leading zeros. This kind of padding is common in data formats that require fixed-width fields, such as databases, file systems, and cataloging schemes, to keep alignment and sorting predictable.

In mathematics, 17 is a prime number and the seventh prime. It is also a Fermat prime. Its standard representations include binary 10001, octal 21, decimal 17, hexadecimal 11, and Roman numeral XVII. The number’s properties and representations make it a convenient example in number theory and computer science discussions.

In computing and information systems, 0017 frequently appears as an identifier, code, or index where a uniform width is important. Leading zeros preserve numeric order when values are compared as text, aid in lexicographic sorting, and help maintain consistent formatting in inventory numbers, version labels, and file names such as 0017.txt or 0017-01.

If interpreted as a year, 0017 would correspond to the year 17 CE in the Julian calendar, placing it in the early first century. While there is no single topic universally associated with the code 0017, its use as a padded form of 17 makes it a common reference in technical and archival contexts.
