Frequently Asked Questions
Why use this instead of a regular calculator?
Standard JavaScript numbers lose precision above about 9 quadrillion; this uses BigInt arithmetic to keep large whole-number results exact.
Does this support decimals?
No, this version handles whole numbers only — decimal inputs are rounded before the calculation.
