0b11110000

0b11110000 is a binary literal that encodes the 8-bit pattern 11110000. In hexadecimal this pattern is 0xF0, and in unsigned decimal it equals 240.

If interpreted as an 8-bit signed value using two's complement, 0b11110000 represents -16. The same bit pattern therefore has different numeric meanings depending on whether it is treated as unsigned or signed data.

In many programming languages, the 0b prefix denotes a binary literal, allowing direct specification of a binary value. For example, 0b11110000 is commonly used in demonstrations of bitwise operations, masking, and bit shifts.

The bit pattern 11110000 has a distinct nibble structure: the upper nibble (bits 7–4) is 1111 and the lower nibble (bits 3–0) is 0000. This makes it a convenient example of nibble-level manipulation and alignment, such as testing high-bit flags or configuring 8-bit registers.

In encoding contexts, 0xF0 (the same byte in hexadecimal) is not part of standard ASCII. In ISO-8859-1 (Latin-1), the byte 0xF0 maps to the Latin small letter eth (ð). In UTF-8, 0xF0 is a leading byte for a four-byte sequence and cannot stand alone as a valid character.

0b11110000 thus serves as a simple, well-known byte pattern used to illustrate binary notation, numeric interpretation under different signedness, and practical bitwise operations in computing. See also binary literals, two's complement, and hexadecimal notation.
