0x2f3

0x2F3 is a hexadecimal numeric literal commonly used in programming to denote the decimal value 755. When interpreted as a hex constant, the digits are 2, F, and 3; calculating its value: 2×16^2 + 15×16 + 3 = 512 + 240 + 3 = 755. In binary, it is 1011110011; when using a fixed width representation in a typical modern system, it is often shown as 0000 0010 1111 0011 in a 16-bit format.

Usage: In languages such as C, C++, Java, JavaScript, and Python, a value prefixed with 0x is treated as hexadecimal. 0x2F3 can be used wherever an integer is required, such as constants, array indices, or bitwise operations. Because 0x2F3 equals 755, it is larger than 255, so it does not fit in an 8-bit unsigned byte by itself; it requires at least 10 bits. In contexts like memory addressing or as part of larger constants, 0x2F3 may appear alongside other hex digits.

In Unicode notation, code points are usually written as U+02F3 rather than 0x2F3. Hexadecimal notation is case insensitive, so 0x2f3 and 0x2F3 denote the same value. See also hexadecimal notation and numeric literals in programming languages.
