Convert any decimal into a fraction reduced to lowest terms. A tunable maximum denominator keeps repeating or irrational decimals (like 0.333 or π) practical instead of exploding into huge denominators.
Decimals to lowest-terms fractions with adjustable max denominator.
Continued-fraction approximation bounded by max denominator, then GCD reduction
| Symbol | Meaning |
|---|---|
| x | Decimal to convert |
| max | Largest allowed denominator (1–100000) |
0.75 → 3/4. 0.333 with max denominator 100 → 1/3.
