0x189B

0x189B is a hexadecimal numeral commonly used in computing to denote a specific 16-bit value. In decimal form, this value equals 6299. In binary, it is represented as 0001 1000 1001 1011. The 0x prefix indicates hexadecimal notation in many programming languages and data formats.

In source code, 0x189B can appear as a literal value. For example, in languages such as C, C++, Java, or JavaScript, a declaration might read: int v = 0x189B;. The value assigned to v would be 6299. Hex literals like 0x189B are frequently used for bitwise operations, masks, color specifications, memory addresses, or low-level hardware configuration where precise bit patterns are important.

Endianness is a relevant consideration when 0x189B is stored in memory. In a big-endian system, the two bytes would be stored as 0x18 followed by 0x9B. In a little-endian system, the order is reversed, with 0x9B stored first and 0x18 second. This distinction matters for interpreting raw data dumps, network protocols, and binary file formats.

Possible interpretations beyond a simple numeric literal exist. If interpreted as a Unicode code point (for example, U+189B), it would designate a specific character in the Unicode standard, though the exact glyph depends on the font and rendering environment. In general, however, 0x189B is not tied to a single, widely named entity; it functions primarily as a hexadecimal representation of the numeric value 6299 used across various technical contexts.
