C# .Round()

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

Syntax

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.

Example

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);
  }
}
