0x1AB

0x1AB is a hexadecimal numeric literal commonly used in programming and computing. In decimal, it equals 427. In binary, its value is 110101011. The prefix 0x signals hexadecimal notation in many languages, with digits 0-9 and letters A-F (case-insensitive).

In programming languages, 0x1AB is treated as an integer constant. For example, in C, C++, Java, JavaScript, or Python, code such as int x = 0x1AB; assigns the value 427 to x. It can participate in arithmetic or bitwise operations just like any other integer constant. Its use is common for representing values that align with binary boundaries or for encoding bit patterns, flags, or memory-related values, depending on the program’s context.

Understanding and converting hex literals like 0x1AB is straightforward: multiply each digit by the corresponding power of 16 and sum the results. Because hex is base-16, it is often convenient when dealing with low-level data, such as hardware registers, color components in some contexts, or masks used in bitwise operations.

Notes and caveats: the literal 0x1AB denotes a numeric value, not a fixed meaning outside of its context. Its interpretation depends on the surrounding code and language. Some languages allow leading zeros to denote octal values in older syntax, but modern language definitions typically use 0x to indicate hex explicitly.
