0x3F5

0x3F5 is a hexadecimal literal used in computing to denote the unsigned integer with decimal value 1013. The 0x prefix indicates hexadecimal notation, a convention widely used in programming languages such as C, C++, Java, Python, and JavaScript.

In hex, the digits 3, F, and 5 represent 3×16^2, 15×16^1, and 5×16^0, respectively, which sum to 1013. The value can also be expressed in binary as 0011 1111 0101 (12 bits). In decimal form it is the prime number 1013, a property sometimes noted in number theory contexts.

Common uses of 0x3F5 in code include assigning a constant value, serving as a bit mask, or marking an offset or identifier in data structures. Examples in plain text would resemble: in C, int x = 0x3F5; in Python, x = 0x3F5; in JavaScript, const x = 0x3F5. The exact interpretation of the value depends on the surrounding program logic and data schema, as hex literals are typically just representations of numeric values.

Beyond simple constants, 0x3F5 may appear in documentation, debugging outputs, or configuration files where hexadecimal notation is used to express numeric parameters. While the specific meaning of 0x3F5 can vary, its role as a hexadecimal representation of the decimal value 1013 remains constant across common programming contexts.
