110101101

110101101 is a nine-bit binary numeral. In base-2 notation, it functions as a fixed-length bit string that can represent a number or serve as a data pattern in digital systems. Such strings are commonly used in teaching, hardware design, and data encoding to illustrate bitwise operations and arithmetic.

As an unsigned integer, 110101101 equals 429 in decimal. It also corresponds to the hexadecimal value 0x1AD. If interpreted as a signed nine-bit two's complement value, it represents -83, since the most significant bit carries a weight of -2^8 (−256) and the remaining bits contribute +173, for a total of −83.

The bit pattern has ones in positions 8, 7, 5, 3, 2, and 0, with zeros in positions 6, 4, and 1. The number of ones is six, giving even parity in this representation, a property that can be relevant in error-detecting schemes and parity checks.

Nine-bit patterns like 110101101 are less common than standard widths (8, 16, 32, 64 bits) but can occur in specialized hardware, embedded systems with nonstandard word sizes, or in educational materials illustrating binary arithmetic, bitwise operations, and two's complement interpretation.
