0xA3B

0xA3B is a hexadecimal literal commonly used in computing. The prefix 0x signals that the following digits are in base-16, where the digits include 0–9 and A–F. The three-digit sequence A3B comprises the digits A (10), 3 (3), and B (11). Its decimal value is 2619.

In programming languages such as C, C++, Java, JavaScript, and Python, 0xA3B is used to denote an integer constant. It can participate in arithmetic, comparisons, bitwise operations, and as an index or flag in code. Because hexadecimal notation is often used to reflect binary patterns, such literals appear frequently in low-level programming, debugging output, and documentation illustrating memory layouts or color values.

In hardware and data contexts, short hex values like 0xA3B may appear as memory offsets, port addresses, or parts of broader identifiers. However, as a standalone token, it does not have an intrinsic meaning beyond its numeric value unless defined by the surrounding software or specification.

On blockchains and blockchain-related documentation, 0xA3B by itself is not typically a valid full address. Ethereum and similar networks use longer, fixed-length addresses (for example, 20-byte values shown as 40 hex digits after 0x). Nevertheless, 0xA3B can occur as part of longer hex strings, keys, or examples in tutorials and code samples.
