Exponent Calculator
Enter a base and exponent to calculate a real power locally in your browser.
A QUICK WALKTHROUGH
How to use this tool
- Enter a finite base and exponent within the limits.
- Calculate the power.
- Review the result or a domain/range message.
Real-number contract
Negative bases require integer exponents. Zero to zero and zero to a negative exponent are rejected as undefined here.
Finite range
Bases are limited to ±10¹⁰⁰ and exponents to ±1,000. Overflow and underflow are reported instead of shown as misleading results.
Local calculation
Parsing and arithmetic happen in your browser; inputs are not uploaded or stored.
GOOD TO KNOW
Common questions
Can I use a fractional exponent?
Yes for a non-negative base. A negative base with a non-integer exponent has no real result.
What happens on overflow?
The calculator reports a range error.
