When a node is in belief-bar style, the probability bars will only display 2 significant digits after the decimal point. If you wish to see up to 5 significant digits after the decimal point, Netica can display the most accurate values of all the states in your net.
How to: Select the nodes you are interested in (or no selection for all of them), then choose Report → Beliefs from the menu. If you want to create links so that the Excel numbers change when Netica's beliefs change, use Report → Links to Paste in Excel.
More on linking to Excel.
You can also get the full number of decimal places by generating a Custom Report.
Of course, if you are accessing belief numbers using Netica API, the numbers obtained are always to the full accuracy.
