063

063 is a three-digit string composed of digits 0, 6, and 3. When treated as a number in decimal notation, it is equal to 63, though the leading zero is typically formatting rather than value. Leading zeros are used in many contexts to enforce fixed width codes.

In mathematics and numeral systems, the value 63 is an odd composite number with prime factorization 3^2 × 7. In binary, 63 is 111111; in octal, it is 077; in hexadecimal, it is 3F. If a programming language treats leading zeros as an indication of octal notation, the string 063 could be interpreted as the octal number 63, which equals decimal 51.

063 is commonly used as a code or identifier in databases, inventories, catalogs, and similar systems. As a three-digit label, it can designate a specific item, category, or entry within a fixed-width numbering scheme. The exact meaning of such a code is determined by the conventions of the system that employs it, not by the digits alone.

Related topics include the plain number 63, numerical codes with fixed width, and the distinction between decimal and other base representations. In contexts where leading zeros carry special meaning, 063 may take on interpretations tied to octal or formatting rules rather than a straightforward decimal value.
