C# Decimal.Floor()用法及代碼示例

此方法用於將小數點四舍五入為負無窮大的最接近的整數。

用法: public static decimal Floor (decimal d);

參數:
d:此參數指定要四舍五入的小數。


返回值:如果d具有小數部分,則小於d或d的負整數的下一個整數十進製數沒有小數部分,則d不變地返回。請注意,該方法返回Decimal類型的整數值。

以下示例程序旨在說明Decimal.Floor(Decimal)方法的用法:

示例1:

// C# program to demonstrate the 
// Decimal.Floor(Decimal) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring the decimal variable 
        Decimal a = 4.01m; 
  
        // finding the floor of the Decimal value 
        // using floor() method; 
        Decimal value = Decimal.Floor(a); 
  
        // Display the Floor 
        Console.WriteLine("Floor Value is : {0}", 
                                          value); 
    } 
}
輸出:
Floor Value is : 4

示例2:

// C# program to demonstrate the 
// Decimal.Floor(Decimal) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring the decimal variable 
        Decimal a = -5.03m; 
  
        // finding the floor of the Decimal value 
        // using floor() method; 
        Decimal value = Decimal.Floor(a); 
  
        // Display the Floor 
        Console.WriteLine("Floor Value is : {0}", 
                                          value); 
    } 
}
輸出:
Floor Value is : -6

示例3:

// C# program to demonstrate the 
// Decimal.Floor(Decimal) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring the decimal variable 
        Decimal a = 2.00m; 
  
        // finding the floor of  
        // the Decimal value 
        // using floor() method; 
        Decimal value = Decimal.Floor(a); 
  
        // Display the Floor 
        Console.WriteLine("Floor Value is : {0}", 
                                          value); 
    } 
}
輸出:
Floor Value is : 2
