0x8019

0x8019 is a hexadecimal literal used in computing to represent a 16‑bit value. The 0x prefix indicates base-16 notation, and the digits 8019 specify the value. In decimal, this equals 32793, and in binary it is 1000 0000 0001 1001.

When stored in memory, the endianness of the system affects the byte order of 0x8019. On a little-endian system, the bytes appear as 0x19 followed by 0x80; on a big-endian system, they appear as 0x80 followed by 0x19. This locality of representation matters when interpreting raw data or debugging low-level code.

In practice, 0x8019 is not a universal constant with a single predefined meaning. It serves as a general 16-bit value that can be used as a status or error code, an identifier in a protocol, a magic number in a file format, or any other context where a fixed 16-bit code is needed. The exact interpretation depends on the documentation, specification, or codebase that defines its usage.

Because the same four hexadecimal digits can have different meanings across systems, it is important to consult the relevant reference when encountering 0x8019 in logs, firmware, drivers, or network communications. Without context, it is simply a numeric constant.
