111111100011

111111100011 is a binary numeral consisting of 12 bits. As a compact bit pattern, it is frequently used in discussions of digital representations and binary encoding.

In decimal form as an unsigned binary number, it equals 4067. In hexadecimal it is 0xFE3, and in octal 0o7743. The bit structure is seven 1s followed by three 0s and ending with two 1s, corresponding to bits 11–5 set, bits 4–2 cleared, and bits 1–0 set.

Under 12-bit two's complement interpretation, 111111100011 represents −29.

12-bit patterns such as this can arise in older computing hardware, embedded systems, and digital signal processing, where registers or data buses are wider than 8 bits. However, the sequence 111111100011 has no widely recognized meaning beyond its numeric value and bit configuration.
