Standard calculators and even JavaScript's regular numbers lose precision beyond about 15-17 significant digits. This calculator uses arbitrary-precision integer arithmetic instead, so numbers with hundreds or even thousands of digits are calculated exactly, with no rounding or precision loss.
Only whole numbers (no decimals) are supported, and division returns an integer quotient plus a remainder rather than a decimal result, since converting an arbitrary-precision division into a decimal would reintroduce the precision limits this tool is designed to avoid.
This calculator works with exact whole numbers of unlimited size. A decimal result could require infinite digits to represent exactly, so division instead returns a whole-number quotient and the remainder.
This calculator supports numbers up to 2,000 digits, and results from multiplication or exponentiation are capped at 2,000 digits as well, to keep calculations fast in your browser.
No, only whole numbers (integers) are supported, positive or negative, with no decimal point.
