0xFA1

0xFA1 is a hexadecimal numeric literal commonly encountered in computing. The 0x prefix signals that the digits following it are in base-16, and the value FA1 corresponds to decimal 4001. In binary, the value is 111110100001. Hexadecimal notation is widely used in programming for compactly representing binary data and memory addresses.

In source code, 0xFA1 may appear as an initializer, a constant, or an offset. For example, in C or C++, int x = 0xFA1; would assign the unsigned value 4001 to x, depending on the type. As a memory address or offset, its meaning depends on the architecture, addressing mode, and endianness. It is not a standard color code or widely meaningful identifier beyond the numeric value, and its interpretation is context-specific.

In broader contexts, the 0x prefix is common in programming languages and in blockchain-related tools to denote hexadecimal values or addresses. However, a short sequence like FA1 is usually not a complete address or hash; longer strings are typically used for those purposes.
