0b1000000010011

0b1000000010011 is a binary literal, a numeric value written in base-2 using the 0b prefix. This form is commonly used in programming languages such as Python and certain C-family languages to distinguish binary notation from decimal or hexadecimal representations.

The sequence consists of 13 bits. Its decimal value is 4115, and it corresponds to the hexadecimal value 0x1013. The bit pattern has ones in the following positions when counting from zero at the least significant bit: bits 0, 1, 4, and 12. In other words, the number is equal to 2^12 + 2^4 + 2^1 + 2^0.

As a binary constant, 0b1000000010011 can be used as a numeric value in arithmetic expressions or as a bitmask for flagging multiple boolean options in software. In hex, it is compactly written as 0x1013, which sometimes aids readability for developers working with low-level data or memory-mapped interfaces. The exact interpretation of this value depends on the context, such as signed versus unsigned representation, the width of the integer type, or its use as a set of bit flags.
