Verifizierter Rechner mit transparenter Formel
Fraction to Decimal Calculator.
Converts a fraction (numerator and denominator) into its decimal equivalent, with optional rounding to a specified number of decimal places.
Ihre Eingaben
So funktioniert es
- 1
Enter the numerator (top number) of the fraction.
- 2
Enter the denominator (bottom number) — must be non-zero.
- 3
Choose how many decimal places you want in the result.
- 4
The calculator divides numerator by denominator and rounds to the chosen precision.
round(numerator / denominator * pow(10, rounding)) / pow(10, rounding)Häufig gestellte Fragen
What if the denominator is zero?
Division by zero is undefined. The calculator requires a non-zero denominator; if you enter zero, the result is not meaningful.
How does rounding work?
The result is rounded to the number of decimal places you specify using standard rounding rules (half up).
Can I convert a mixed number?
This calculator handles proper and improper fractions. For a mixed number, convert it to an improper fraction first (e.g., 1 1/2 becomes 3/2).

Tipps und häufige Fehler
Tips
- If the denominator is a power of 10 (like 10, 100, 1000), the decimal is easy: just move the decimal point.
- For repeating decimals, you may want to use more decimal places to see the pattern.
- Use the unrounded result for further calculations to avoid rounding errors.
Common Mistakes to Avoid
- Forgetting that the denominator cannot be zero.
- Confusing numerator and denominator — the numerator is divided by the denominator.
- Rounding too early in multi-step calculations, which can accumulate errors.
Annahmen und Einschränkungen
- Use the stated inputs and units.
- Results are estimates for planning and education.
- Check measurements and source data before making an important decision.
