Frequently asked questions
How are repeating decimals like 1/3 shown?
Repeating digits aren't marked specially — the result is computed to 10 decimal places with trailing zeros trimmed. For example, 1/3 displays as 0.3333333333. If you need more precision, try the fraction directly rather than relying on the decimal output.
Is a decimal always converted to a fraction in lowest terms?
Yes. The numerator and denominator are divided by their greatest common divisor so the result can't be simplified further.
What happens if I enter 0 as the denominator?
You'll see a validation error, since division by zero is undefined. The denominator must be a nonzero integer.
