What bitwise operations are supported?

AND, OR, XOR, NOT (bitwise complement), left shift ( >). Each operation works on binary, octal, decimal, and hex inputs.

How big can the numbers be?

Arbitrary precision — uses JavaScript BigInt internally, so there's no overflow. Works on numbers of any size.

What bases are supported?

Binary (base 2), Octal (base 8), Decimal (base 10), and Hexadecimal (base 16). Input A and Input B can use different bases, and the output can be in any base.

What does left shift do?

Left shift by n bits multiplies the number by 2^n. Right shift by n bits divides by 2^n (integer division, drops the remainder).

Quick reference

& AND — bit is 1 only if both inputs are 1

| OR — bit is 1 if either input is 1

^ XOR — bit is 1 if inputs differ

~ NOT — inverts all bits

<< n Left shift — multiply by 2^n

>> n Right shift — divide by 2^n
