0x195A

0x195A is a hexadecimal numeric literal commonly encountered in computing and programming. The prefix 0x denotes base-16, and the digits 1, 9, 5, and A (with A representing 10) encode the value. The number 0x195A equals 6490 in decimal. In binary, it is 0001 1001 0101 1010, reflecting its 16-bit representation.

As a 16-bit quantity, 0x195A often appears in source code as a constant used for bit masks, offsets, or small enumeration values. It can participate in bitwise operations, such as 0x195A & 0x00FF, which yields 0x005A, illustrating how hex literals facilitate manipulation of specific bits or bytes. In some contexts, 0x195A might also denote a memory address or a hardware register offset, depending on the architecture and programming language.

Compared with decimal literals, hexadecimal literals like 0x195A are frequently preferred when describing low-level bit patterns, binary protocols, or hardware interfaces because they map cleanly to byte and word boundaries. In many languages, 0x195A is treated equivalently to the decimal 6490, differing mainly in formatting and type representation.
