0x3FA

0x3FA is a hexadecimal integer literal commonly encountered in computing and digital electronics. In decimal, it equals 1018, and in binary, it is 1111111010. The hexadecimal format uses a 0x prefix to distinguish hex values from decimal numbers.

In software and hardware contexts, 0x3FA can represent a variety of things depending on the surrounding system. It may denote a memory address in a program, a register offset in a peripheral's map, an I/O port number, or a bit mask used in low-level operations. The exact meaning is determined by the architecture, the programming language, and the documentation for the hardware or software being used.

0x3FA sits near 0x3FF (which is 1023, or 2^10−1), making it relevant in discussions of 10-bit data, masking, or boundary conditions. It can be expressed as 0x400 minus 0x6, illustrating how hex values relate to adjacent hexadecimal boundaries.

Notes on notation: the prefix 0x indicates hexadecimal, and the digits 0–9 and letters A–F are used to represent values. Like many hex literals, 0x3FA has no single universal meaning on its own; its interpretation depends entirely on context within a given system or codebase.
