Rounds the input to the nearest integer.
If the value of the input is midway between two integers (for example, 1.5 or 2.5), the function returns the nearest even integer (2). The connector pane displays the default data types for this polymorphic function.

Refer to the Add - Various Uses VI in the labview\examples\general\functions\Numeric directory for an example of using the Round To Nearest function.
