0b1000100001001

0b1000100001001 is a binary integer literal that uses the 0b prefix to indicate base-2 notation in several programming languages. The sequence contains 13 bits.

In decimal form, the value is 4361, and in hexadecimal it is 0x1109. The bit pattern has 1s at positions 12, 8, 3, and 0 (counting from 0 as the least significant bit), corresponding to 2^12, 2^8, 2^3, and 2^0.

As an unsigned 13-bit number, 0b1000100001001 equals 4361. If interpreted as a signed 13-bit two's complement value, the magnitude would be negative: 4361 - 2^13 = -3831. In many practical contexts, the value is treated as an unsigned integer unless a specific signed interpretation is required.

Context and usage: binary literals like this are commonly used in programming to specify bit patterns and masks precisely. Such literals can be useful in bitwise operations, testing, and configuring low-level flags or hardware interfaces where individual bits carry meaning.

Language support: the 0b prefix is supported in many modern languages, including Python, JavaScript (ES6 and later), C++14 and newer, Rust, and Go, among others. This enables direct representation of binary constants without manual conversion.

Summary: 0b1000100001001 is a 13-bit binary constant representing the unsigned value 4361 (0x1109), with 1-bits at 12, 8, 3, and 0, and it may be interpreted differently depending on the chosen numeric context.
