Numerical value: In decimal, 0x15C1 equals 5569. Its binary representation is 0001 0101 1100 0001, and it can be interpreted as a 16‑bit quantity.

Context and usage: Without context, 0x15C1 may appear as a constant in source code, an address in a memory map or an identifier in a data structure. It can function as a bitmask or as part of low-level hardware registers, depending on the architecture and language. In software examples, such literals are common in C, C++, Java, and many scripting languages.

Unicode mapping: If treated as a Unicode code point, the value 0x15C1 corresponds to the code point U+15C1, which lies in the Canadian Aboriginal Syllabics block. It designates a specific syllabic character used in some Indigenous Canadian writing systems. In Unicode contexts, code points are usually written as U+15C1 rather than 0x15C1, but numerically they refer to the same value.
