0b10010111001001

0b10010111001001 is a binary numeral literal commonly used in programming to denote the value in base-2. The prefix 0b signals a binary representation, and the bits are 14 digits long, making it a 14-bit value.

In decimal notation, this binary value equals 9673. In hexadecimal, it is 0x25C9. The set bits occur at positions 13, 10, 8, 7, 6, 3, and 0 (counting from zero at the least-significant bit).

Usage in languages: Many modern languages support 0b prefixes to create binary literals, including Python 3, JavaScript (ES6+), and newer editions of C and C++. The length of the binary literal does not imply a fixed width; it represents an integer value that can be used in arithmetic or bitwise operations.

Applications: As a bit mask, a literal like 0b10010111001001 could be used to enable or test specific bits in a larger data word. It is also useful in examples of binary-to-hex and binary-to-decimal conversion, and serves as a simple illustration of base-2 representation.
