Factor 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
- To find factors, we check every number from 1 up to the square root of the target number ($n$). If a number $i$ divides $n$ evenly ($n \% i == 0$), then both $i$ and $n/i$ are factors. This method is efficient for finding all pairs.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Number: 24
Expected outputs
- Factors: 1, 2, 3, 4, 6, 8, 12, 24
- Count: 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 input should be a positive whole number.
- Factors are listed as positive divisors only.
- Zero is not supported because every number divides 0 evenly and the factor list would be undefined.
Unit handling
- Number accepts numeric values.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
