1000100101

1000100101 is a ten-bit binary numeral. In unsigned form, it represents the decimal value 549, and in hexadecimal it corresponds to 0x225.

The bits set to 1 occur at positions 9, 5, 2, and 0 when counting from the least significant bit as position 0. The Hamming weight (number of 1s) is four. The 10-bit length places this pattern between typical 8-bit and 16-bit representations used in computing.

In practical terms, 1000100101 is not tied to a specific standard character encoding or widely used instruction. It can appear as a sample bit pattern, a data word, or a bitmask in digital logic and communications. As a test vector, it is suitable for illustrating bit extraction, parity checks, or masking operations in teaching and debugging contexts.

If interpreted as a signed value in a 10-bit two's-complement representation, 1000100101 would denote -475. This highlights how the same bit pattern can represent different values depending on the numeric interpretation.

The decimal value 549 factors as 3^2 × 61, a mathematical property of the number rather than the binary form. Beyond numeric interpretation, the string serves mainly as an example of a 10-bit binary sequence and is typically used for demonstrations, testing, or as a simple reference in discussions of binary arithmetic.
