0x137F

0x137F is a hexadecimal literal commonly used in computing to represent the integer value 4991. The prefix 0x signals hexadecimal notation in many programming languages, including C, C++, JavaScript, Python, and others.

In software and hardware contexts, a value like 0x137F may appear as a constant, a memory address, an offset, or a bitmask. Its exact meaning is determined by the surrounding code, the data width (for example 8, 16, or 32 bits), and how the value is interpreted by the system or application.

As a 16‑bit value, 0x137F has the binary representation 0001 0011 0111 1111, illustrating which bits are set. If interpreted differently—for instance as part of a larger register or in an endianness-dependent process—the same hex string can map to different byte orders or meanings.

In practice, 0x137F is a generic numeric literal. It is typically encountered in tutorials, low-level programming, configuration contexts, or debugging output, where the reader must consult specific domain documentation to determine its function.
