dotnet-bot Math.Round Method (System) Rounds a value to the nearest integer or to the specified number of fractional digits. Notice the entry for Math.Round (Decimal, MidpointRounding): "Rounds a decimal value to the nearest integer. A parameter specifies how to round the value if it is midway between two other numbers." So if you were calling System.Math.Round(x), you just change your call and add one parameter: System.Math.Round(x,System.MidpointRounding.AwayFromZero); And now you know.
