Why a Separate Big Number Calculator?
Ordinary calculators (and JavaScript's regular numbers) only store about 15-17 significant digits exactly - beyond that, results start rounding and losing precision. This calculator uses arbitrary- precision integer math instead, so whole numbers with dozens or even hundreds of digits are added, subtracted, multiplied, divided, or raised to a power with an exact result, not an approximation.
Notes on Division
Division between two whole numbers here is integer division: the result is the whole quotient plus the remainder, since a big integer can't represent a fractional part exactly. Exponents must be whole, non-negative numbers.
