What's the largest number this calculator can handle?

There's no theoretical limit to the size of numbers this calculator can handle. The practical limit depends on your device's memory and processing power. Numbers with thousands of digits are typically no problem.

Why do I need a big number calculator?

Standard calculators and computers have limits (usually 64-bit integers or double-precision floats). For cryptography, mathematical research, or working with very large datasets, you need arbitrary precision arithmetic.

How does big number arithmetic work?

Big number libraries store numbers as arrays of digits and implement arithmetic algorithms that work digit by digit, similar to how you might do long multiplication by hand but optimized for computers.

Are the results exact or approximate?

For addition, subtraction, and multiplication, results are exact. Division may be rounded to a certain number of decimal places. The calculator will indicate when rounding occurs.
