Exponent Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- * **Positive Integer:** $x^n = x \times x \dots$ (n times). * **Negative Exponent:** $x^{-n} = 1 / x^n$. * **Fractional Exponent:** $x^{1/n} = \sqrt[n]{x}$.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Base: 2
- Exponent: 3
Expected outputs
- Power Value: 8
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- The base and exponent are finite real numbers.
- The result follows standard real-number behavior from JavaScript's power function.
- Some inputs, like 0^0 or negative fractional powers, are mathematically undefined or may return NaN.
Unit handling
- Base accepts numeric values.
- Exponent accepts numeric values.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
