0xB

0xB is the hexadecimal literal representing the decimal value 11. The prefix 0x is commonly used in programming to denote that the following digits are in base 16, where the digits 0–9 represent values zero through nine and the letters A–F (often written upper or lower case) represent values ten through fifteen. In this system, B represents the value eleven.

In binary terms, 0xB corresponds to 1011. In an 8-bit byte, this value is often written as 0x0B to emphasize the full byte width, though many languages treat 0xB the same as 0x0B. The relationship among representations is: decimal 11 equals hex 0xB, which equals binary 1011.

Programming usage and contexts: 0xB is a common form for numeric literals in many languages, including C, C++, Java, JavaScript, and Python. It is frequently used in low-level tasks such as bitwise operations, bit masks, flag fields, and index calculations. Because hex digits align neatly with four-bit groups (nibbles), hexadecimal notation is convenient for expressing binary patterns and memory-related values.

Limitations and clarifications: while 0xB is a valid literal, its interpretation depends on the language and context, but it generally represents the integer value eleven. Hexadecimal literals are separate from decimal literals and from other base notations; they should be distinguished when parsing or converting values in software systems. In color codes or larger numeric constants, 0xB may appear as part of a longer hexadecimal sequence rather than as a stand-alone value.
