FAQ: How to convert a decimal to a fraction?

CALC will automatically convert or estimate a fraction representation of a decimal number as long as it's bellow one thousand. You can see this in the upper left corner (the Tip/Suggestion section) of the results area of the screen (right bellow the Options button in the corner there).

If you tap in the area, you will be presented with a list of options to choose from to adjust your preferences.
