Frequently Asked Questions
Decimal, binary, hexadecimal, and octal — enter a value in any one field and the rest update automatically.
AND, OR, XOR, NOT, and left/right bit shift, calculated on two decimal input values.
Hex is commonly used for color codes and memory addresses, binary for low-level bit manipulation, and octal occasionally for legacy file permission systems — this tool avoids doing the conversion by hand.
Standard decimal-to-other-base conversions work for positive integers; bitwise operations follow standard two's complement behavior for negative values.
Very large numbers are supported, though extremely large values may be limited by JavaScript's standard number precision.
