Which fraction formats can I enter?
Enter whole numbers, simple fractions such as 3/4, or mixed numbers such as 2 1/3.
How are fraction results simplified?
The numerator and denominator are divided by their exact greatest common divisor after every operation.
Can I convert decimals and fractions?
Yes. Convert a finite decimal with up to 12 decimal places or display a fraction as a decimal.
How are negative mixed numbers handled?
A leading negative sign applies to the complete mixed number, so -2 1/3 becomes -7/3.
