1010111001

1010111001 is a binary numeral consisting of ten bits. In base-2 notation it represents a concrete value used in computing and digital systems. The number is odd, and its ten-bit length places it within the range of unsigned integers from 0 to 1023.

In decimal, 1010111001 equals 697. In hexadecimal it is 0x2B9, and in octal it is 1271. These representations reflect the same value expressed in different numeral systems. The most significant bit is 1, and the least significant bit is also 1, indicating its odd parity.

The binary pattern contains a run of three consecutive 1s in the middle (the bits around the center). The bit sequence reversed is 1001110101, illustrating that the string is not a palindrome. As a fixed-length bit string, 1010111001 can serve as a sample value in demonstrations, tests, or datasets, and may function as a test vector for conversions between binary, decimal, hexadecimal, and octal, or as a simple identifier in a data set.

In contexts where a specific encoding scheme is defined, the meaning of 1010111001 would depend on that scheme. Absent a prescribed interpretation, it is treated as a generic ten-bit binary value. See also binary numeral system, bit, and base conversion for related concepts.
