0x9C9

0x9C9 is a hexadecimal literal commonly encountered in computing. The prefix 0x signals that the following digits are in base 16. The value 0x9C9 equals the decimal number 2505. In binary, it is 1001 1100 1001. This notation appears in many programming languages such as C, C++, JavaScript, and Python for numeric constants, bitwise operations, and memory addressing.

In color terminology, hex values are also used to specify colors, typically in the forms #RRGGBB or the shorthand #RGB. The sequence 0x9C9 is not a standard color code by itself. However, in some contexts a numeric hex value could be interpreted as color data if parsed by a specific software system, depending on how many bits are allocated for color components.

In blockchain and smart contract contexts, the 0x prefix is common for addresses and identifiers. Nevertheless, Ethereum-style addresses are 42 characters long, starting with 0x, and a short string like 0x9C9 would not constitute a valid address on its own. It may appear as a sample value, a fragment of code, or as part of documentation or testing data rather than as an actual address.

Etymology: The 0x prefix is a conventional indicator of hexadecimal numbers in many programming languages, while 9C9 is a 3-digit hexadecimal number using the digits 0–9 and letters A–F.
