Worked example
Operation: Add a: 1/3 b: 1/6
→ 1/2 ≈ 0.5
Method and scope
Enter integer fractions as a/b, up to 1,000 digits per integer. Signs are normalized. The exact fraction and signed mixed-number magnitude precede a rounded decimal. Zero denominators are rejected.
a/b + c/d = (ad + bc)/bd
Precision and limits
≈ marks an approximation. Display rounding does not change the internal calculation.
