Accuracy – number of decimal places. Rounding is according to mathematical rules.
Minimum and maximum values – define the range, which limits the value of the field. When you enter a value, outside of the range, a notification is shown (fig. 4). The value will be automatically changed to the minimum or the maximum value (whichever is closer to the entered value).
