0xD45

0xD45 is a hexadecimal literal that can appear in various computing contexts. The prefix 0x signals that the following characters are written in base-16. The digits D, 4, and 5 form the value, and in decimal it equals 3397.

As a numeric value, 0xD45 represents 13 × 16^2 + 4 × 16 + 5, which computes to 3397. In most programming languages, such literals are used directly in expressions, assignments, and data structures, and they participate in arithmetic, bitwise operations, and memory addressing as appropriate to the language and environment.

In blockchain and smart contract ecosystems, the 0x prefix is commonly used to denote hex-encoded data or addresses. However, a short literal like 0xD45 is typically not a valid full address in systems that require fixed-length addresses (for example, 20-byte Ethereum addresses). Instead, it may appear as part of a larger hex string or as a data field within a transaction.

Other contexts include computing and documentation where 0xD45 might be encountered as a fragment of longer hex strings, or as a shorthand in examples illustrating hex notation. It is distinct from color notation in CSS, where a 3-digit hex color would be written as #D45 (not 0xD45), expanding to #DD4455 if interpreted as a shorthand color.
