C# Double.IsFinite()用法及代碼示例

Double.IsFinite()方法用於檢查double值是否超出範圍。

用法： public static bool IsFinite (double value);

返回值：如果值是有限的，則此方法返回true，否則返回false。

下麵的程序說明Double.IsFinite()方法的使用：

示例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); 
    } 
}

輸出：

10 is finite

示例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); 
    } 
}

輸出：

Infinity is not finite
