079

079 is a three-digit numeral whose decimal value is 79. In many applications, a leading zero is used to enforce fixed-width formatting, so "079" is often used as an identifier or code rather than as a standalone number.

79 is a prime number, the 22nd prime, with divisors only 1 and itself. This mathematical property remains the same whether the number is written as 79 or 079 in decimal notation, since leading zeros do not change value.

As a year, AD 79 (79 CE) denotes a historical date notable for the eruption of Mount Vesuvius, which destroyed Pompeii and Herculaneum. When used in historical timelines, the leading zero is typically a formatting choice rather than a distinct year.

In computing and data storage, 079 is frequently used as a fixed-width code in inventories, product SKUs, or document numbers; the leading zero helps maintain consistent length and can aid lexicographic sorting in databases and file systems.

In telephone and numbering plans, a leading zero is commonly used as a trunk prefix in many countries. Consequently, "079" may appear as part of a longer domestic number, depending on the national system and dialing conventions.

Overall, the significance of 079 is contextual, functioning as a numeric value, a calendar reference, or a fixed-width identifier across different domains. See also: 79, leading zeros, prime numbers.
