Buy me a coffeeWhat is AND Calculator?
AND Calculator computes the bitwise AND operation between two integers. It accepts input in decimal, binary, hexadecimal, or octal and returns the result in all four bases. A visual bit-pattern diagram shows how AND is applied bit by bit. The calculator uses unsigned 32-bit arithmetic (operands are coerced with >>> 0), consistent with how JavaScript and most embedded systems handle bitwise operations.
How to Use AND Calculator
1
Select the input base.
2
Enter two numbers.
3
The AND result appears in all four bases below.
Common Use Cases
- Extracting specific bits from a register value using a bitmask.
- Checking whether specific flags are set in a bitfield.
- Computing subnet masks in networking calculations.
- Verifying bitwise AND behavior for hardware register programming.
Example Input and Output
12 AND 10 in decimal.
A=12, B=10 (decimal)
A: 12 (1100₂)
B: 10 (1010₂)Result
AND: 8 (1000₂)Privacy

Frequently Asked Questions
What does bitwise AND do?
Bitwise AND compares each bit position of two operands. The result bit is 1 only when both corresponding input bits are 1. All other bit positions produce 0.
Why does the result use unsigned 32-bit?
Bitwise operators in JavaScript convert operands to signed 32-bit integers before operating, then >>> 0 converts the result to unsigned 32-bit for display. This matches the behavior in C/C++ unsigned int operations.
