0xAFB

0xAFB is a hexadecimal literal commonly used in computing to denote a numeric value. The prefix 0x signals that the following digits are in base-16, which is a standard notation in many programming languages for representing integers and addresses.

As a value, 0xAFB corresponds to decimal 2811. This is calculated as 10×256 + 15×16 + 11, since hex digits A, F, and B represent 10, 15, and 11 respectively. In binary, 0xAFB is 1010 1111 1011, a 12-bit pattern (with leading zeros possible for wider word sizes). It can also be written as 0x0AFB in contexts that prefer uniform width representations.

In programming, hex literals like 0xAFB are supported by many languages, including C, C++, Java, JavaScript, and Python. Examples include int x = 0xAFB; in C or C++, and x = 0xAFB in Python, which evaluates to the decimal value 2811. Such literals are commonly used for memory addresses, bit masks, flags, and other constants where hexadecimal notation offers a compact representation of binary patterns.

Beyond its function as a numeric constant, 0xAFB does not denote a widely recognized organization, standard, or term. Its interpretation is context-dependent, arising from the surrounding code, data structures, or protocol specifications in which the literal appears.
