Prime Factorization 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
- The calculator divides the number by the smallest possible prime (2), then continues dividing by primes (3, 5, 7, etc.) until the quotient is 1. The result is displayed as a multiplication string (e.g., 2 × 2 × 3).
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Number: 60
Expected outputs
- Prime Factors: 2 × 2 × 3 × 5
- Is Prime?: No
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
- This calculator only supports positive integers greater than 1.
- Decimal, blank, and non-finite inputs return an invalid result instead of being truncated.
- The factor list uses repeated prime factors, so 12 appears as 2 × 2 × 3.
Unit handling
- Number accepts numeric values.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Input precision follows configured step values where provided.
