111001101

111001101 is a nine-bit binary number. When interpreted as an unsigned integer, it has the decimal value 461, and in hexadecimal it corresponds to 0x1CD. The bit pattern from most significant to least significant is 1, 1, 1, 0, 0, 1, 1, 0, 1. The number has a Hamming weight of 6 and is an odd value since the least significant bit is 1.

In binary arithmetic, 111001101 can be expressed as the sum 2^8 + 2^7 + 2^6 + 2^3 + 2^2 + 2^0. This representation highlights its composite contributions across different bit positions. If interpreted as a signed value using nine-bit two's complement representation, the same bit pattern represents -51, because 111001101 corresponds to the unsigned value 461, and in a 9-bit two's complement system values above 255 wrap into the negative range (461 - 512 = -51).

Uses and interpretation of such a string depend on context. It can serve as an arbitrary bit pattern, a data word, or a bitmask in systems with 9-bit wide data paths. It is not associated with a standard character encoding (ASCII uses 7 or 8 bits), but it can appear in examples illustrating binary, hexadecimal, or two's complement arithmetic.
