MathF.Round() Method in C# with Examples
The MathF.Round() method in C# is used to round a value to the nearest integer or to the particular number of fractional digits.
Syntax
Following is the syntax −
public static float Round (float x); public static float Round (float x, int digits); public static float Round (float x, int digits, MidpointRounding mode); public static float Round (float x, MidpointRounding mode);
Example
Let us now see an example to implement the MathF.Round() method −
using System;
public class Demo {
public static void Main(){
float val1 = 15.20f;
float val2 = 3.10f;
Console.WriteLine("Rounded (val1) = "+MathF.Round(val1));
Console.WriteLine("Rounded (val2) = "+MathF.Round(val2));
}
}Output
This will produce the following output −
Rounded (val1) = 15 Rounded (val2) = 3
Example
Let us now see another example to implement the MathF.Round() method −
using System;
public class Demo {
public static void Main(){
float val1 = 10.23898f;
float val2 = 20.878788f;
Console.WriteLine("Rounded (val1) = "+MathF.Round(val1,2));
Console.WriteLine("Rounded (val2) = "+MathF.Round(val2,3));
}
}Output
This will produce the following output −
Rounded (val1) = 10.24 Rounded (val2) = 20.879
