The Math.Round() class method returns a value rounded to the nearest integer.


Math.Round(value1, value2, value3);

The Math.Round() method takes up to three parameters:

  • value1 is the only required parameter and is either a decimal or double.
  • value2 would be an integer ranging from -2,147,483,648 to 2,147,483,647 (int32), or it could be a specific mode that is called from the MidpointRounding enum.
  • value3 would be the mode if value2 was of type int32. The modes include: ToEven, AwayFromZero, ToZero, and TowardZero.


The following example passes one argument as a parameter:

using System;
public class Example {
public static void Main(string[] args) {
decimal val1 = 10.2m;
val1 = Math.Round(val1);
Console.WriteLine("Rounded value is " + val1);

The example will result in the following output:

Rounded value is 10
