MathF.Log() Method in C# with Examples

The MathF.Log() method in C# is used to return the logarithm of a specified number.

Syntax

Following is the syntax −

public static float Log (float val);

Above, Val is the specified number whose natural (base e) logarithm to be calculated.

Example

Let us now see an example to implement the MathF.Log() method −

using System;
public class Demo {
   public static void Main(){
      float val1 = 0.0f;
      float val2 = 1.0f;
      Console.WriteLine(MathF.Log(val1));
      Console.WriteLine(MathF.Log(val2));
   }
}

Output

This will produce the following output −

-Infinity
0

Example

Let us now see another example to implement the MathF.Log() method −

using System;
public class Demo {
   public static void Main(){
      float val1 = 45.9f;
      float val2 = -4.35f;
      Console.WriteLine(MathF.Log(val1));
      Console.WriteLine(MathF.Log(val2));
   }
}

Output

This will produce the following output −

3.826465
NaN
