0xF0

0xF0 is a hexadecimal literal used in computing to denote the value F0 in base 16, with the prefix 0x indicating hexadecimal notation. It is commonly found in programming languages and digital systems to represent a byte-sized value or part of a larger bit pattern.

Numerically, 0xF0 equals 240 in decimal. In an 8-bit byte context, this is the unsigned value 240. If the same 8-bit value is interpreted as a signed number using two's complement representation, it corresponds to -16.

In character encoding terms, the Unicode code point U+00F0 corresponds to the Latin small letter eth, Ð with the lowercase form shown as ð in many fonts. This code point is also represented by the byte 0xF0 in the ISO/IEC 8859-1 (Latin-1) character set. In UTF-8, however, the single byte 0xF0 is not a complete character; it serves as the leading byte for a four-byte sequence encoding code points from U+10000 to U+10FFFF (for example, the character U+1F600, the grinning face, is encoded as F0 9F 98 80).

In programming practice, 0xF0 is used in hex literals to specify bit masks, flags, or byte-oriented values. Languages such as C, C++, Java, JavaScript, and Python permit expressions like 0xF0 to represent the value 240, often in conjunction with bitwise operations to manipulate binary data.
