C# Single.IsFinite()用法及代碼示例

Single.IsFinite()方法用於檢查float值是否超出範圍。

用法： public static bool IsFinite (float value);

返回值：如果值是有限的，則此方法返回true，否則返回false。

以下示例程序旨在說明Single.IsFinite()方法的使用：

示例1:

// 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); 
    } 
}

輸出：

1654.268 is finite

示例2:

// 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); 
    } 
}

輸出：

Infinity is not finite
