Using Exact Binary & Hex Arithmetic Calculator
Add, subtract, multiply or divide large binary, hexadecimal or decimal integers with exact results, integer quotients and remainders.
- Start with the example and choose the declared input representation and any bit width.
- Change the operation or format, then inspect the precise result and validation messages.
- Copy the output or download text, JSON or a CSV audit. Save a project to retain editable inputs.
Example
FFFFFFFFFFFFFFFF + 1 = 10000000000000000 in hex, exactly. 17 divided by 5 gives quotient 3 and remainder 2.
Questions & answers
Are large integer results exact?
