111001111

111001111 is a binary numeral consisting of nine bits. In decimal, it equals 463, and in hexadecimal it is 0x1CF. As a nine-bit value, it is often treated in contexts that use non-standard or arbitrary bit widths, rather than typical 8- or 16-bit word sizes.

The pattern contains seven 1s and two 0s, with the two zeros occurring consecutively in the middle (111 00 1111). The most significant bit (the leftmost) is 1, and the least significant bit (the rightmost) is also 1, giving it a dense, high-ones composition.

In computing, such a pattern can arise as a specific bit pattern in a 9-bit field, used as a binary flag set, a custom mask, or as part of an encoding scheme in specialized hardware or software. When interpreted as a bit mask, the two zero bits correspond to cleared positions, while the remaining bits are set.

111001111 does not correspond to a standard ASCII or Unicode character encoding, since those schemes use fixed widths like 7, 8, or 16 bits for characters. Nine-bit widths are uncommon in modern text encoding but can appear in custom hardware designs, simulation environments, or educational examples illustrating binary representation and bitwise operations.

The sequence is sometimes encountered in puzzles, demonstrations of binary arithmetic, or discussions about data encoding and bit patterns. Its value and structure are straightforward to derive from binary notation and can serve as a simple example of a dense bit pattern.
