0b100001010010

0b100001010010 is a binary integer literal commonly used in programming languages that support base-2 notation. The prefix 0b (or 0B in some languages) indicates that the digits that follow represent a binary value rather than decimal.

The binary digits are 100001010010. This value equals 2130 in decimal and 0x852 in hexadecimal. In binary grouping, it can be read as 1000 0101 0010, highlighting the set bits at positions 11, 6, 4, and 1 (counting from 0 for the least significant bit).

As a 12-bit pattern, the leading bit is 1, which would indicate a value above 2048 if interpreted in a fixed-width unsigned format. In practice, the width of the literal depends on the language and the surrounding type; the number is typically stored in a standard integer type, such as 32-bit or 64-bit, with the lower 12 bits matching this pattern.

Use cases for such literals include defining bitmasks, flags, or hardware-related constants where specific bits are on or off. They are also convenient for expressing constants without converting from decimal.
