0x158B

0x158B is a hexadecimal numeral commonly encountered in computing. In decimal, it equals 5515. In binary, it is 0001 0101 1000 1011. The prefix 0x is widely used in programming languages such as C, C++, Java, and JavaScript to denote hexadecimal literals.

In software development, such literals appear as explicit constants, bit masks, memory addresses, or identifiers within low-level code, as well as components of data encoded in hexadecimal notation. The exact meaning of 0x158B depends on the context; it could be part of a memory address, an opcode, a flag set, or a value in a protocol specification. Without contextual information, the sequence 0x158B has no intrinsic meaning beyond its numeric value.

In various domains, hexadecimal values serve as compact representations of binary data, facilitate debugging, and aid in interpreting machine instructions. Endianness can affect how such a value is stored in memory or transmitted over a network, but it does not change the value itself; it only changes its byte order when serialized.

As a general practice, hexadecimal literals like 0x158B are part of the broader set of numeral systems used in computer science, alongside decimal, binary, and octal. See also hexadecimal notation, 0x-prefix conventions, and 16-bit number representation.
