0994

0994 is typically read as the decimal number 994 when the leading zero is not significant. As a numeric value, 994 is even and composite.

In number theory, 994 factors as 2 × 7 × 71, making it squarefree. Its positive divisors are 1, 2, 7, 14, 71, 142, 497, and 994. The sum of all divisors is 1728, so the sum of proper divisors is 734, which is less than 994. Therefore, 994 is a deficient number. Its representations in common bases are: binary 1111100010, octal 1742, and hexadecimal 3E2. In Roman numerals, 994 is written as CMXCIV.

The string 0994 can also function as a four-digit label or year-like token in various contexts. If interpreted as a year, it corresponds to 994 CE, a point in the middle of the 10th century, a period during which contemporary regions experienced significant historical developments.

In computing and typography, leading zeros such as in 0994 are sometimes used to enforce fixed-width formatting or as part of an identifier. In many programming languages that use a leading zero to denote octal literals, the sequence 0994 cannot be parsed as a valid octal value because the digit 9 is not allowed in octal notation; as a result, 0994 is typically treated as an invalid numeric literal or as a string in such contexts, depending on the language.
