Formula Used in Pi Game Calculator
This tool uses mathematical comparison and error analysis formulas.
1. Absolute Difference Formula
Difference = |π − Guess|
This calculates how far your guess is from the real value of π.
2. Accuracy Score Formula
Score = (1 − (Difference ÷ π)) × 100
This formula converts error into a percentage score.
- Closer guess = higher score
- Larger error = lower score
3. Rounding Formula
To compare digits accurately:
Rounded Value = Math.round(Value × 10ⁿ) ÷ 10ⁿ
Where:
- n = number of digits selected
This ensures both values are compared fairly at the same precision level.
Example Calculation Table
| Your Guess | Digits Compared | Actual π | Difference | Accuracy Score |
|---|---|---|---|---|
| 3.14 | 2 | 3.141593 | 0.001593 | 99.95% |
| 3.141 | 3 | 3.141593 | 0.000593 | 99.98% |
| 3.15 | 2 | 3.141593 | 0.008407 | 99.73% |
| 3.142 | 3 | 3.141593 | 0.000407 | 99.99% |
| 3.2 | 1 | 3.141593 | 0.058407 | 98.14% |
