ConverterFraction to Decimal
Enter a numerator and denominator as an integer fraction such as -7/8. The converter uses BigInt arithmetic to preserve the operands, simplifies the exact fraction, and labels the decimal as terminating or repeating.

Terminating And Repeating Examples
| Fraction | Decimal | Type |
|---|---|---|
| 1/2 | 0.5 | Terminating |
| 3/8 | 0.375 | Terminating |
| 1/3 | 0.333... | Repeating |
| 2/7 | 0.285714... | Repeating |
Why Integer Operands Are Deliberate
A fraction is accepted as two signed integers so the exact numerator and denominator can be represented without first passing through JavaScript Number.
Mixed numbers and decimal operands can be rewritten as integer fractions before entry. This keeps the grammar narrow and avoids silently guessing how a copied expression should be interpreted.
Tool-Specific Accuracy Notes
Fraction to Decimal is built for quick planning and verification, but the result is only as reliable as the input values and assumptions used on the page.
- Keep the original inputs with any copied result so the calculation can be reviewed later.
- Use this calculator for pre-checks, estimates, and workflow support, not as a replacement for official review.
- Recalculate after correcting dates, units, decimal places, or eligibility cutoffs.
Frequently Asked Questions
Use signed integers separated by one slash, such as 3/4 or -7/8. Decimal operands and mixed-number notation are intentionally rejected.
After simplification, a fraction terminates in base 10 only when the denominator has no prime factors other than 2 and 5.
No. The normalized fraction remains exact. A repeating decimal preview is rounded to 18 decimal places and labeled accordingly.
No. Division by zero is undefined, so the converter rejects a zero denominator.
Verify the original inputs, date or eligibility assumptions if relevant, rounding, and whether your use case requires an official or institution-specific method.
