111110001

111110001 is a nine-bit binary string. It consists of five consecutive ones, followed by three zeros, and terminating with one.

In unsigned interpretation, the string equals 497 in decimal. When interpreted as a nine-bit two's complement number, it represents -15.

Hexadecimal and encoding: As a 9-bit value padded to 12 bits, it can be represented as 0x1F1; in standard 16-bit form it is 0x01F1.

Applications and notes: Such patterns may arise as test vectors in digital logic, for example to exercise decoders, shift registers, or parity checks. The distribution of ones and zeros makes it useful for testing bit-level differences and for evaluating pattern matching or run-length encoding schemes. However, by itself the sequence has no widely recognized special meaning in mathematics or science.
