0xF55

0xF55 is a hexadecimal numeral commonly encountered in computing. The prefix 0x indicates base-16 notation in many programming languages. The value equals 3925 in decimal. It consists of three hex digits (F, 5, 5), representing 12 bits. In binary this is 111101010101.

Applications: As a generic constant, 0xF55 may appear as an immediate value, a part of a memory address, or a baseline example in tutorials about hex arithmetic. Because it is a 12-bit value, it falls within the range 0x000 to 0xFFF. There is no widely recognized standard, protocol, or device specifically identified by 0xF55 alone.

Related notes: In contexts using CSS-like color shorthand, the three-digit hex 0xF55 would be written as F55 and, if interpreted as a color code, expands to #FF5555. In general, hex numbers are written with 0x in programming languages or with a # prefix in some other contexts; the exact usage depends on the language and convention.
