How to use the Exponent Calculator
The base is the number being raised and the exponent determines the power. Positive integer exponents represent repeated multiplication. A negative exponent takes the reciprocal of the corresponding positive power. Decimal exponents are supported for non-negative bases using real-valued floating-point arithmetic. Enter a negative base directly rather than adding parentheses or an expression.
The calculation
Worked example
2^10 is 1,024. 2^−3 is 0.125. A negative base raised to an odd integer stays negative, while an even integer produces a positive result.
Assumptions and limits
The calculator leaves 0^0 undefined by convention, rejects zero raised to a negative exponent, and accepts only integer exponents for a negative base. Some negative-base fractional powers can be defined through particular rational interpretations, but this page does not infer those representations. Non-finite numerical results are rejected instead of displaying infinity.
Common questions
Why is 0^0 rejected?
Its interpretation depends on context. This calculator chooses to leave it undefined rather than silently applying a programming convention.
Can I calculate a negative exponent?
Yes, as long as the base is non-zero. For example, 10^−2 is 0.01.
