What is a terminating decimal?

A terminating decimal has a finite number of digits after the decimal point — for example, 1/4 = 0.25. A fraction produces a terminating decimal when its denominator (in lowest terms) has no prime factors other than 2 and 5.

What is a repeating decimal?

A repeating decimal has one or more digits that repeat forever — for example, 1/3 = 0.333... Any fraction with a denominator containing prime factors other than 2 and 5 will produce a repeating decimal.

Can I enter negative fractions?

Yes. Put a minus sign in either the numerator or the denominator field. If both are negative the result is positive, matching standard sign rules.

Can I convert a mixed number like 2 3/4?

Enter the improper fraction form instead: 2 3/4 = (2×4 + 3) / 4 = 11/4. The calculator will give 2.75.

How many decimal places does it show?

Up to 10 decimal places. For repeating decimals the tool shows 10 places and notes the repeating pattern.

What happens if the denominator is zero?

Division by zero is undefined. The calculator shows an inline error and will not produce a result.
