Double.IsFinite() Method in C#

  • Last Updated : 15 Apr, 2019
Geek Week

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
