Random Number 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 the browser's built-in `Math.random()` function, which generates a floating-point number between 0 and 1. We scale this to your range using the formula: `Result = Math.floor(Math.random() * (Max - Min + 1)) + Min`
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Minimum: 1
- Maximum: 100
Expected outputs
- Generated Number: 34
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
- Minimum and maximum should be finite whole-number bounds.
- The minimum value must be less than or equal to the maximum value.
- Results use the browser's pseudo-random generator, which is appropriate for casual use but not cryptographic security.
Unit handling
- Minimum accepts numeric values.
- Maximum accepts numeric values.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
