0b1000011000

0b1000011000 is a binary integer literal expressed with a 0b prefix, a notation used in several programming languages to denote numbers written in base 2. The sequence consists of ten binary digits, representing the value directly in binary form.

Numerically, the binary pattern 1000011000 corresponds to the decimal number 536. In hexadecimal, it is 0x218. The pattern has ones at bit positions 9, 4, and 3 when counting from zero as the least significant bit, with all other positions cleared.

Common uses for such a literal include representing a bitmask, an offset, or a literal value to be used in bitwise operations. For example, as a mask it would enable bits 9, 4, and 3 while leaving other bits cleared, depending on how it is applied in code.

The 0b prefix is supported by numerous languages, including Python, JavaScript (since ES2020), C++, Rust, and others, where the prefix signals a binary literal. The exact interpretation—such as the effective width and how the value is stored—depends on the language and the surrounding type context. In most languages, the literal is treated as an integer value, and its bit-width is determined by how the compiler or runtime represents integers.
