0x3AA

0x3AA is a hexadecimal numeric literal commonly encountered in computing. The 0x prefix denotes base 16, so the digits that follow—3, A, and A—encode the value 3×16^2 + 10×16 + 10, which equals 938 in decimal. In binary this value is 1110101010, and in octal it is 1652.

In programming languages that use C-style hex literals, 0x3AA is parsed as an integer constant. For example, in Python you can write x = 0x3AA and x will hold the integer 938. In C or Java, int x = 0x3AA; similarly, many languages support hex literals in arithmetic, comparisons, and bitwise operations, enabling concise representation of masks and flags.

The 0x3AA notation is not tied to a specific meaning by itself; its interpretation depends on context. It might appear as a numeric constant in algorithms, as a memory address or offset in documentation, or as part of a multi-byte value in low-level data structures. Because it uses the digit A (which stands for 10 in hexadecimal), it is often used in examples to illustrate hexadecimal digits beyond decimal 9.
