111000010

111000010 is a binary numeral consisting of nine bits. As an unsigned binary number, it equals 450 in decimal; in hexadecimal it is 0x1C2; in octal it is 0o702.

In the context of a nine-bit two's complement representation, the bit pattern 111000010 corresponds to -62. This illustrates how the same bit sequence can represent different values depending on whether it is treated as unsigned or signed.

In modern computing, data is typically stored in 8-bit bytes, so nine-bit sequences are uncommon. They may appear in specialized architectures, in packed bit fields, or as parity or control bits in certain error-detection schemes. Nine-bit formats can arise in communication protocols or legacy systems that reserve extra bits for redundancy or formatting purposes.

The pattern can also serve as a compact example for illustrating binary-to-decimal conversion and the impact of sign interpretation in two's complement. It demonstrates how a leading set of ones influences the signed value and how the same bits map to different numerical representations in hex and octal.
