0xFE3

0xFE3 is a hexadecimal integer literal used in programming and computing. It denotes the decimal value 4067, and in binary it corresponds to the 12-bit pattern 111111100011. In languages that use the 0x prefix for hex, such as C, C++, Java, JavaScript, and Python, 0xFE3 can appear in code as a constant, for example in bitwise operations, array indexing, memory addressing, or as part of a numeric constant.

Because hex literals are commonly used to express bit masks and hardware registers, 0xFE3 may be used to enable or test a subset of bits depending on the surrounding width. Its interpretation can vary with the bit width and signedness: if stored in a width where the top bit of the value is the sign bit (for example a 12-bit signed integer), it would represent a negative value; in typical 16-bit or larger signed integers it represents 4067.

In practice, 0xFE3 does not imply any universally standardized meaning outside a specific context; its significance is derived from how it's used within a given program or hardware interface. Because it is a relatively small, three-digit hex value, it is often included in examples demonstrating hex to decimal conversion, bitwise operations, and representation across bases (binary, octal, decimal, hex).
