0x163D

0x163D is a hexadecimal numeric literal commonly used in computer science and information technology. In decimal form, it represents 5661. The value can be split into two-byte components: 0x16 and 0x3D, corresponding to binary 00010110 and 00111101, and the full 16-bit pattern 0001011000111101.

Hexadecimal literals like 0x163D appear in source code across languages such as C, C++, JavaScript, and Python, where they initialize constants, memory addresses, or bit patterns used in low-level operations, configuration registers, or data encoding. In broader contexts, hex values are often used as shorthand for bit masks to extract or set specific bits within a word.

Endianness affects how such a value is stored in memory. In little-endian architectures, the least significant byte (0x3D) is stored first, followed by 0x16; in big-endian systems, the bytes appear as 0x16 then 0x3D.

Because 0x163D is simply a hexadecimal representation of a number, its meaning is context-dependent and cannot be determined from the value alone. See also hexadecimal numeral system, endianness, memory address, and bitmask.
