100111011

100111011 is a binary numeral composed of nine digits, using only the symbols 0 and 1. When interpreted in base-2, it represents the decimal value 315. In hexadecimal, it equals 0x13B. As a nine-bit pattern, it sits within the common binary representations used in computing and digital systems.

The binary string contains six ones and three zeros, giving a population count (bit count) of 6. It is not a palindrome, since reversing the sequence yields 110111001, which is different from the original. The corresponding decimal value 315 factors as 3^2 × 5 × 7.

In practical terms, 100111011 can serve as an example of a nine-bit binary value in computing, digital logic, or data encoding. Nine-bit patterns can code a range of values from 0 to 511, so 315 corresponds to a mid-range address or constant within such a scheme. It can be used in programming examples, hardware description language demonstrations, or discussions of bit-pattern representations.

Notes and related concepts include the binary numeral system in general, binary-to-hexadecimal conversion (0x13B in this case), and the idea of bit patterns used for addressing, masking, or flag sets in digital electronics. See also: binary numeral system, hexadecimal notation, bit patterns.
