0xF9D

0xF9D is a hexadecimal numeric literal that appears in software source code and other digital contexts. The prefix 0x is widely used in programming languages such as C, C++, Java, Python, and JavaScript to indicate that the following digits are in base-16. The digits F, 9, and D correspond to the decimal values 15, 9, and 13, respectively. As a hexadecimal number, 0xF9D equals 3997 in decimal.

In software, a literal like 0xF9D can serve as a constant, an address offset, a bit mask, or an opcode parameter, depending on the surrounding code and the architecture involved. In low-level contexts and assembly language, the value may be used to specify an immediate value or a memory location.

0xF9D is sometimes encountered in discussions of color notation when people refer to short, three-digit hexadecimal color codes. If interpreted as a 3-digit hex color without the 0x prefix, F9D expands to the full six-digit color #FF99DD. Note that standard CSS color notation uses the 3-digit or 6-digit hex form and does not include the 0x prefix in actual color values; the prefix is a programming convention rather than a color specification.

There is no widely recognized product, standard, or organization specifically named “0xF9D.” It is primarily encountered as a hexadecimal literal representing the decimal value 3997 in various computing contexts. See also hexadecimal, hexadecimal literals, and color notation.
