Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Points Earned: 450
- Points Possible: 500
Expected outputs
- Percentage: 90.00%
- Letter Grade: A
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 assumes every point in the class is worth the same amount.
- Entered possible points should include only graded work that counts toward the class total.
- If your class uses weighted categories instead of raw totals, a weighted grade calculator will be more accurate.
Unit handling
- Points Earned accepts numeric values.
- Points Possible accepts numeric values.
- Percentage is displayed as a percentage.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Percent outputs are displayed with two decimal places.
