Single.IsFinite() Method in C# with Examples

Last Updated : 01 May, 2019

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

Syntax: public static bool IsFinite (float value); Return Value: This method returns the true if value is finite otherwise false.

Below programs illustrate the use of Single.IsFinite() Method: Example 1:

csharp

// C# program to demonstrate the
// Single.IsFinite() Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        float value1 = 1654.268416f;

        // using IsFinite() method
        bool value = Single.IsFinite(value1);

         // Displaying the result
        if (value)
            Console.WriteLine("{0} is finite", value1);
        else
            Console.WriteLine("{0} is not finite", value1);
    }
}

Output:

1654.268 is finite

Example 2:

csharp

// C# program to demonstrate the
// Single.IsFinite() Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        float value1 = (float)Math.Pow(2, 10000000);

        // using IsFinite() method
        bool value = Single.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
