0xA4A

0xA4A is a hexadecimal numeric literal commonly encountered in computer programming and digital data representation. The prefix 0x indicates that the following characters are written in base-16. The digits A, 4, and A correspond to decimal values 10, 4, and 10, respectively; evaluating the hex number yields 10×16² + 4×16 + 10 = 2634. In most languages, the literal 0xA4A is equal to 0xa4a, since hexadecimal notation is case-insensitive.

Usage of 0xA4A appears in source code as a constant in arithmetic, bitwise operations, or as an offset. It can also show up in debugging output, memory dumps, or when printing addresses in hexadecimal. Although arbitrary, 0xA4A is a valid constant in any language that supports hexadecimal literals, and its meaning is determined by the surrounding program context.

Notes and related concepts: Hex values are commonly used to represent binary data, memory addresses, or masks. In some contexts, hexadecimal values may also relate to color codes (for example, short hex color #A4A expanding to #AA44AA in certain shorthand interpretations). The interpretation of 0xA4A therefore depends on how and where it is used within a given software system.
