🔢 Big Number Calculator
Add, subtract, and multiply arbitrarily large integers with exact precision using BigInt arithmetic.
Working with Large Numbers
Standard JavaScript numbers lose precision beyond 2^53 − 1 (about 9 quadrillion). This calculator uses BigInt arithmetic to handle integers of any size with exact precision, making it ideal for cryptography, combinatorics, and scientific computations involving very large values.
Limitations
This calculator works with integers only. Division returns the integer quotient (floor division). For decimal operations with large numbers, specialized libraries are needed. BigInt operations are supported in all modern browsers.
