0x820

0x820 is the hexadecimal representation of the integer 2080. In many programming languages, the leading 0x indicates a base-16 literal, so 0x820 is a valid numeric constant in languages such as C, C++, Java, JavaScript, and Python. As a value, it may be used as an arithmetic quantity, a bitmask, a flag selector, or an identifier within binary data formats or protocol messages.

The exact meaning of 0x820 is context-dependent. In a protocol specification, it could designate a particular command or status code. In a low-level program, it might represent a memory offset or an address component. When shown in logs or debug outputs, systems may also display its decimal equivalent (2080) or its binary form (1000 0010 0000).

Because hexadecimal is a compact way to express binary data, literals like 0x820 frequently appear in debugging dumps, configuration files that encode numeric options, and hex editors. Its significance is not intrinsic to the number itself but derives from the system, standard, or document in which it is used.
