2 ^ 100
= 1267650600228229401496703205376
The exact power is larger than a standard 64-bit integer.
Large Number Power Calculator
Calculate exact large powers with whole-number exponents, including decimal bases and scientific-notation inputs.
How this calculation works
Exponentiation multiplies a base by itself the stated number of times. A zero exponent returns one under this calculator’s convention. Decimal bases remain exact rational values throughout the calculation.
Inputs and accuracy
Enter a non-negative whole-number exponent. Estimated results above two million digits are blocked before allocating an enormous answer. Bases 0, 1, and −1 have bounded results even for large positive exponents.
When to use it
Inspect powers of two for binary capacities, check repeated-growth calculations, and explore integer exponentiation without silently overflowing ordinary number formats.
Worked examples
1.5 ^ 3
= 3.375
A decimal base produces an exact rational result.
