0x2AA

0x2AA is a hexadecimal literal used in computing to denote a specific integer value. In hex notation, the prefix 0x signals base-16, and the digits 2, A, A correspond to 2, 10, 10 respectively. The decimal value of 0x2AA is 2×256 + 10×16 + 10 = 682.

In binary, 0x2AA is represented as 0010 1010 1010 in a 12-bit form (three hex digits × 4 bits each). In broader contexts such as memory dumps or debugging output, 0x2AA may appear as an address offset, a constant, or a value used in demonstrations of hexadecimal arithmetic. Because it contains the sequence AA, it is sometimes chosen in examples for its recognizability and readability.

In programming languages that support hexadecimal literals (for example, C, C++, Java, JavaScript, Python), 0x2AA can be used wherever an integer constant is allowed. It is not a special constant with inherent mathematical significance beyond its numeric value, but its nontrivial mix of bits can make it convenient for illustrating bitwise operations, masking, or testing, where hexadecimal notation often aids readability.

Overall, 0x2AA is primarily notable as a concrete example of a hex constant representing the decimal number 682. There is no widely acknowledged entity or standard uniquely associated with the name 0x2AA; if a particular project or dataset uses this label, additional context would be needed to identify its specific meaning.
