0x494

0x494 is a hexadecimal literal that represents a 16‑bit unsigned integer. In the Base‑16 number system the digits 0–9 and the letters A–F are used to encode values from 0 to 15, so 0x494 equates to the decimal value 1220. Converting the value from base‑16 to base‑10 is done by evaluating each digit’s contribution using powers of sixteen: 4×16² + 9×16¹ + 4×16⁰, which yields 1220.

In computing and digital electronics the notation 0x494 is occasionally employed as a memory‑address or configuration‑register identifier, particularly in embedded systems where memory maps are expressed in hexadecimal for clarity. For example, on some microcontrollers the register at address 0x494 might control a peripheral interface or hold a status flag. Because 0x494 lies within the lower half of the 16‑bit address space, it often corresponds to a register that drivers or low‑level firmware directly access.

The value 0x494 also appears as a common representation in programming documentation and debugging output. Languages such as C, C++, C#, and Java use the prefix 0x to denote hex constants; thus code snippets that declare an integer like int value = 0x494; illustrate how the compiler interprets the literal as decimal 1220. In runtime logs, a system printing an address or error code may display 0x494 to succinctly convey a value within a 16‑bit word.

Because hexadecimal notation offers a human‑readable, compact form for binary values, 0x494 is sometimes mentioned in documentation of assembly code, firmware binaries, or hardware specifications. While it has no special properties beyond its numeric value, it serves as an example of how hexadecimal representation facilitates direct mapping between binary data, memory addresses, and software interfaces.
