How Is Rounding Applied in the Calculations?

In all calculations, all decimals stored for that data type are being used and finally rounded as requested in the selected settings. Forsta Visualizations uses Round-half-up symmetric logic. Below you can find examples of the rounding that is applied.

Half-even Rounding

Half-even rounding, also known as bankers rounding, is an additional rounding method. This method rounds halfway values to the nearest even number, as demonstrated by examples when rounding to integers or one decimal place. The applied rounding method is a project level setting and is applied to all calculations in StoryTeller, including Respondent table, Crosstable Tool, and StoryCreator. To apply half-even rounding, simply go to the Project settings page, select Calculations and Result menu, and activate “round half to even” in the new rounding section.
