| C# Example |
using System;
public class MathRoundExample
{
public static void Main()
{
Double d1 = Math.Round(4.4);
Double d2 = Math.Round(4.5);
Double d3 = Math.Round(4.6);
Console.WriteLine("Math.Round(4.4) returns {0}", d1);
Console.WriteLine("Math.Round(4.5) returns {0}", d2);
Console.WriteLine("Math.Round(4.6) returns {0}", d3);
}
}
