0xFF9

0xFF9 is a hexadecimal numeral commonly encountered in computing. The prefix 0x indicates base-16 notation, so the digits FF9 denote the numeric value 4089 in decimal. In binary, 0xFF9 corresponds to 111111111001, a 12-bit pattern. In most modern programming languages, 0xFF9 is interpreted as an integer literal, with its value being 4089, the exact interpretation (signed or unsigned) depending on context and type.

As a literal, 0xFF9 is frequently used in code for low-level operations such as bitwise manipulation, masking, shifting, or as a constant in memory-address computations. It can appear in debugging outputs, hex dumps, or any situation where a precise hexadecimal value is more convenient than a decimal one. In languages with explicit unsigned types, the literal is treated as an unsigned value; in others, it is stored in a signed integer of an appropriate size, but the numeric value remains 4089.

In color and graphics contexts, hexadecimal color values typically use six digits (for 24-bit color) or three-digit shorthand. A standalone 0xFF9 does not correspond to a standard 24-bit color, though it could be part of a larger sequence or a 12-bit color representation in specialized formats.

Leading zeros can be added for alignment or formatting (for example, 0x0FF9) without changing the value. Overall, 0xFF9 is primarily a numeric constant rather than a concept with an independent meaning beyond its decimal value.
