0xFFDC

0xFFDC is a hexadecimal literal commonly used in computing and digital electronics. The 0x prefix indicates hexadecimal notation in many programming languages, including C, C++, Java, JavaScript, and Python. The value of 0xFFDC in decimal is 65,500. In binary, it is 11111111 11011100, representing a 16-bit word.

When interpreted as a signed 16-bit integer using two’s complement, 0xFFDC corresponds to -36. This dual interpretation—unsigned versus signed—illustrates how the same bit pattern can have different meanings depending on context, a common consideration in low-level programming and data interpretation.

In practical use, 0xFFDC may appear as a 16-bit data word, a memory address fragment, or a constant in source code used for bitwise operations, masking, or register values. It often serves as an example value in documentation, tutorials, or discussions of numeric representations, rather than conveying a specific, universal meaning.

If interpreted as a 16-bit RGB color in the 5-6-5 format, the value encodes red, green, and blue components with specific bit allocations (red 5 bits, green 6 bits, blue 5 bits). The resulting color depends on the encoding and the target display, and different systems may map these components differently.

There is no widely recognized significance attached to 0xFFDC beyond its role as a hexadecimal constant. Its importance is determined by the surrounding context, including the architecture, data formats, and software in which it appears.
