Convert a Fraction to a Decimal

Converting a fraction to a decimal is division wearing a different hat: 3/4 is 0.75, 1/3 is 0.333..., 22/7 is 3.142857... Every fraction p/q turns into a decimal that either stops - when the reduced denominator only factors as 2s and 5s - or repeats its digits forever. Either way, the conversion is exact arithmetic, not estimation.

Convert a Fraction to a Decimal divides numerator by denominator and hands back the decimal form with the decimal places you choose. Optionally it marks the recurring block - 0.(285714) - so a repeating fraction shows its true infinite value. Batch up to 1000 fractions per run.

• Exact division: The true value, not an approximation.
• Place control: 0 to 20 decimal places of display.
• Repeating block: Parenthesised cycle: 0.(3), 0.(142857).
• Terminates when it can: Clean finite decimals when the fraction allows.
• Batch mode: Up to 1000 fractions per run.
• Copy or download: Export every result.

1. Enter the numerator - the top of the fraction.
2. Enter the denominator - the bottom, never zero.
3. Choose decimal places - how many digits to display.
4. Toggle the block - show repeating cycles exactly.
5. Generate and read - the decimal form.

1. 3/4: 0.75 - two places, terminating exactly.

2. 1/3: 0.333... - repeating; the block shows 0.(3).

3. 22/7: 3.142857... - the pi approximation, repeating block 0.(142857).

4. 1/8 with 3 places: 0.125 - clean, terminating.

5. 5/2: 2.5 - improper fraction becomes a decimal with a whole part.

• True values: Division shows what the fraction really equals.
• Readable repeats: Parenthesised cycles beat endless ellipses.
• Place flexibility: Coarse or fine output, your call.
• Batch power: Hundreds of conversions at once.
• Copy or download: Every result exports in one click.
• Private and free: All arithmetic stays in the browser; nothing is uploaded or logged.
