0x21B9

0x21B9 is a hexadecimal numeral often encountered in computing and digital text. In base-16 notation, the prefix 0x indicates a hex value, so 0x21B9 corresponds to the decimal number 8633.

In Unicode, the hexadecimal code point U+21B9 maps to a character in the Arrows block. The exact appearance of the symbol is font-dependent, as fonts provide different designs for arrow-like characters. The Arrows block, which contains U+21B0 through U+21FF, is used to represent directional indicators and related glyphs in text and mathematical notation.

As a numeric literal, 0x21B9 is used in many programming languages to specify a value in hexadecimal form. It may appear in source code for data values, bitwise operations, memory addressing, color specifications, or other low-level computations where hex representation is convenient. When interpreted by a compiler or interpreter, the literal translates to the integer value 8633 in decimal.

In encoding contexts, the character associated with U+21B9 is included in Unicode and can be used in text streams, documents, and user interfaces that require consistent symbol rendering across platforms. Like other Unicode symbols, its visual rendering relies on the font used by the application or system.
