Dice Roller 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 uses a pseudo-random number generator (PRNG) to produce an integer between 1 and the number of sides for each die. Formula per die: `Math.floor(Math.random() * sides) + 1`
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Type: D6 (Cube)
- Number of Dice: 1
Expected outputs
- Total Sum: 4
- Individual Rolls: 4
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 number of dice must be a positive whole number.
- This tool simulates standard fair dice with equally likely sides.
- Results come from the browser's pseudo-random generator, which is suitable for casual use but not for audited or cryptographic randomness.
Unit handling
- Type accepts one of the configured options.
- Number of Dice accepts numeric values.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
