0xA09

0xA09 is a hexadecimal numeric literal commonly encountered in computing. Interpreted as a base-16 value, it equals the decimal number 2569. Its exact binary representation is 1010 0000 1001.

In most programming languages, the prefix 0x denotes a hexadecimal constant. For example, in C, C++, Java, JavaScript, and Python, writing 0xA09 assigns the integer value 2569 to a variable. These literals are widely used to express values that align with bytes or bit fields, enabling clear specification of masks, offsets, and addresses.

Common contexts for 0xA09 include low-level programming and hardware interfaces, where such constants are used in bitwise operations, memory addressing, and flag configurations. It may also appear in graphics and color coding schemes that apply compact hexadecimal representations, though standard web colors use 3- or 6-digit hex codes without the 0x prefix.

As a numeric literal, 0xA09 has no intrinsic meaning beyond its numeric value unless given context by software, hardware, or data formats. In documentation, code, or datasets, its interpretation depends on how the value is used—e.g., as an address fragment, an opcode, a color component, or a configuration parameter.
