101111110

101111110 is a binary numeral consisting of nine digits. As a bit pattern it can be used to represent a number in digital systems or simply as an example of a binary string in descriptions of bit operations. The sequence contains seven 1s and two 0s, with the most significant bit set to 1 and the least significant bit set to 0.

In decimal the value is 382. In hexadecimal it is 0x17E, and in octal it is 576. The pattern is even, since it ends in 0, and it has a single 0 near the most significant end and another at the least significant end.

If interpreted as a 9-bit unsigned integer, 101111110 represents 382. If interpreted as a 9-bit two’s complement signed integer, its value would be -130. This demonstrates how the same bit pattern can have different numerical meanings depending on the chosen representation.

Applications and significance: as a binary example, 101111110 is useful for illustrating concepts such as binary-to-decimal conversion, hexadecimal and octal representations, and the impact of bit-length on signed versus unsigned interpretation. It can also serve as a concrete pattern in discussions of bit masks, data encoding, or simple digital logic exercises.
