0b010001011001

0b010001011001 is a binary literal commonly used in programming to denote a base-2 numeral. It consists of 12 bits and represents a fixed bit pattern rather than any single agreed-upon meaning without context.

As a value, it equals decimal 1113 and hexadecimal 0x459. The 12-bit grouping 0100 0101 1001 corresponds to the hex digits 4, 5, and 9, which is why the hex representation is 0x459. The most significant bit is 0, so it is non-negative if interpreted as a signed value in a two’s-complement system; in a strictly 12-bit unsigned interpretation, the value remains 1113.

In practical use, a 12-bit pattern like this can serve as a bit mask, a fragment of a larger bitfield, or an encoded data element within compact communication or storage formats. Its exact meaning depends on the surrounding specification or code that processes it. For example, in a language that supports binary literals, it might be combined with other literals to form flags or to pack small fields into a single word.

Notes: the 0b prefix is a common convention in many programming languages to indicate binary literals, including Python, Rust, JavaScript (ES6 and later), and C++14 and newer. Readability can be improved by grouping bits or adding separators in long literals, but the value remains 1113 (0x459) regardless of formatting.
