0016

0016 is the four-digit decimal numeral that encodes the integer 16 when leading zeros are included. The form is common in fixed-width display or storage formats where numbers are aligned to a uniform width, such as serial numbers, inventory codes, timestamps, or data records.

In other numeral systems, the value 0016 equals 16. In binary it is 10000; in octal it is 20; in hexadecimal it is 0x10. The number 16 is a power of two (2^4) and a perfect square (4^2), and it has divisors 1, 2, 4, 8, and 16.

If interpreted as a year, 0016 often refers to the year 16 in the Common Era (16 CE), which falls in the early Roman Imperial period in most Western historical contexts. In historical documentation, years are sometimes written with leading zeros to fit a given column width, rather than implying a different year.

In modern data practices, 0016 can function as a string identifier in databases or software where fixed-width fields are used. As a portable code, it rarely carries itself meaning beyond its numeric value; its significance is determined by the surrounding system or dataset.

There is no widely recognized event or entity uniquely identified by the string "0016." Its relevance is typically contextual, arising from formatting conventions, cataloging schemes, or programming requirements.
