0x2142

0x2142 is a hexadecimal literal commonly used in computing to represent the 16-bit value that equals 8514 in decimal. The prefix 0x signals hexadecimal notation in many programming languages, including C, C++, Java, C#, JavaScript, and Python. As a numeric constant, 0x2142 can be used in calculations, comparisons, and as a parameter in function calls, or it may serve as an identifier or flag within a data structure depending on the program.

In memory, the same value can be stored in different byte orders. On a big-endian system, the two bytes would appear as 0x21 followed by 0x42. On a little-endian system, they would appear as 0x42 followed by 0x21. This endianness affects how low-level data is read from or written to hardware or binary files.

Context largely determines the meaning of 0x2142. It may be used as a constant to configure software, as a memory address or offset in low-level code, or as part of a protocol or data encoding where specific hex values map to certain meanings. There is no universal interpretation for 0x2142 outside a given context, so its significance is defined by the surrounding code, data formats, or specifications in which it appears.
