0xFA0

0xFA0 is a hexadecimal literal commonly used in programming and computing. The prefix 0x indicates that the digits that follow are in base-16. The value of 0xFA0 is 4000 in decimal, and its binary representation is 111110100000. The shorthand digits F, A, and 0 correspond to decimal values 15, 10, and 0, respectively, so the calculation is 15*256 + 10*16 + 0 = 4000.

In source code, 0xFA0 can appear as a constant, such as a numerical parameter, a bitmask, or an address-like value, depending on the language and the variable type. In languages like C, C++, Java, JavaScript, and Python, 0xFA0 is treated as an integer literal. The actual type and range depend on the language and the size of the integer type (for example, 32-bit or 64-bit integers).

Context matters for interpretation: in memory addressing, 0xFA0 could denote a small offset or address within a process's address space; in bitwise operations, it might be used as a mask for lower bits, given that only certain lower hex digits are set.

Leading zeros do not change the value; 0x0FA0 and 0xFA0 are the same number. Some languages allow alternative prefixes or digits when formatting output or parsing input, but 0x remains the canonical indicator for hexadecimal in many C-family languages.
