C＃中的Decimal.Remainder()方法

当在两个指定的十进制值之间进行除法时，使用此方法来计算余数。

Syntax: public static decimal Remainder (decimal a1, decimal a2);

Parameters:
a1: This parameter specifies the dividend.
a2: This parameter specifies the divisor.

Return Value: It returns the remainder of the after dividing a1 by a2.

例外情况：

• DivideByZeroException：当a2为零时发生。
• OverflowException：如果返回值小于MinValue或大于MaxValue 。

下面的程序说明了Decimal.Remainder(Decimal，Decimal)方法的用法：

范例1：

// C# program to demonstrate the
// Decimal.Remainder(Decimal, 
// Decimal) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // Declaring the decimal variables
            Decimal a1 = 4.02m;
            Decimal a2 = 1.11m;
  
            // dividing and getting the remainder
            // of the two Decimal value
            // using Remainder() method;
            Decimal value = Decimal.Remainder(a1, a2);
  
            // Display the remainder
            Console.WriteLine("Remainder is : {0}", value);
        }
  
        catch (OverflowException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

输出：

Remainder is : 0.69

示例2：对于OverflowException

// C# program to demonstrate the
// Decimal.Remainder(Decimal, 
// Decimal) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // Declaring the decimal variables
            Decimal a1 = Decimal.MaxValue;
            Decimal a2 = 0.02m;
  
            // dividing and getting the remainder
            // of the two Decimal value
            // using Remainder() method;
            Decimal value = Decimal.Remainder(a1, a2);
  
            // Display the remainder
            Console.WriteLine("Remainder is : {0}", value);
        }
  
        catch (OverflowException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

输出：

Exception Thrown: System.OverflowException

示例3： DivideByZeroException程序

// C# program to demonstrate the
// Decimal.Remainder(Decimal,
// Decimal) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // Declaring the decimal variables
            Decimal a1 = 4.02m;
            Decimal a2 = 0.00m;
  
            // dividing and getting the remainder
            // of the two Decimal value
            // using Remainder() method;
            Decimal value = Decimal.Remainder(a1, a2);
  
            // Display the remainder
            Console.WriteLine("Remainder is : {0}", value);
        }
  
        catch (DivideByZeroException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

输出：

Exception Thrown: System.DivideByZeroException
