자주 묻는 질문
How do you convert a fraction to a decimal?
Divide the numerator by the denominator. Each step multiplies the remainder by 10 to get the next digit. A zero remainder ends the decimal; a repeated remainder starts the repeating part.
What do parentheses mean?
Parentheses mark the digits that repeat forever. For example, 1/6 is 0.1(6), which means the 6 continues without end.
Can it handle mixed numbers?
Yes. Enter the whole number separately from the numerator and denominator. The tool converts it to an improper fraction before dividing.
Does it use floating point math?
No. It uses BigInt integer arithmetic and remainder tracking, so large fractions stay exact and floating point rounding does not affect the result.
What if the denominator is zero?
A denominator of zero is undefined. The tool shows an error and waits until you enter a non-zero denominator.
Is it free and private?
Yes. It is free, needs no account, and runs in your browser. The numbers are not uploaded.
