0x19A5

0x19A5 is a hexadecimal numeric literal commonly used in computer programming and digital systems. The prefix 0x indicates that the digits that follow are in base 16. The value equals decimal 6565. This exact value may appear in source code, configuration files, or hardware interfaces as a constant, a bit mask, or an address, depending on the context. In languages such as C, C++, Java, JavaScript, Python, and Rust, 0x19A5 denotes an integer literal, with the actual type determined by the language rules and the surrounding code.

Being a four-digit hex number, 0x19A5 fits within 16 bits, but in many environments it will be stored in 8, 16, 32, or 64-bit integers; bitwise operations such as shifting and masking may be applied to extract or combine particular bits or fields. The interpretation of the value is entirely context-dependent, influenced by how it is used in data structures, protocols, or hardware registers.

Unicode note: In Unicode, the code point U+19A5 is in the Khmer Symbols block. It designates a specific Khmer glyph; its appearance and meaning depend on the font and rendering system. This illustrates how hex notations can refer to both numeric values in programming and discrete characters in text encoding when prefixed with 0x in different contexts.

Origins and usage: The 0x prefix originated in the C programming language and has since become common across many languages and tools for representing hexadecimal values. When documenting or exchanging data, it is important to distinguish hexadecimal values (base 16) from their decimal equivalents and from other encoding schemes.
