Double.IsNaN() Method in C#

Double.IsFinite() Method in C#

Last Updated : 15 Apr, 2019

Double.IsFinite() Method is used to check whether the double value is out of bound or not.

Syntax: public static bool IsFinite (double value);

Return Value: This method returns the true if value is finite otherwise false.

Below programs illustrate the use of Double.IsFinite() Method:

Example 1:

// C# program to demonstrate the 
// Double.IsFinite() Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and initializing value1 
        double value1 = 10d; 
  
        // using IsFinite() method 
        bool value = Double.IsFinite(value1); 
  
        // Displaying the result 
        if (value) 
            Console.WriteLine("{0} is finite", value1); 
        else
            Console.WriteLine("{0} is not finite", value1); 
    } 
} 

Output:

10 is finite

Example 2:

// C# program to demonstrate the 
// Double.IsFinite() Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and initializing value1 
        double value1 = Math.Pow(2, 1000000000000); 
  
        // using IsFinite() method 
        bool value = Double.IsFinite(value1); 
  
        // Displaying the result 
        if (value) 
            Console.WriteLine("{0} is finite", value1); 
        else
            Console.WriteLine("{0} is not finite", value1); 
    } 
} 

Output:

Infinity is not finite
