C＃中的Decimal.Divide()方法

此方法用于将两个指定的十进制值相除。

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

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

Return Value: The result of dividing a1 by a2.

例外情况：

• DivideByZeroException ：当a2为零时发生。
• OverflowException ：如果将a1和a2相除的结果小于Decimal的最小可能值或大于Decimal的最大可能值。

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

范例1：

// C# program to demonstrate the
// Decimal.Divide(Decimal,
// Decimal) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // Declaring the decimal variables
            Decimal a1 = 4.02m;
            Decimal a2 = 2.01m;
  
            // dividing the two Decimal value
            // using Divide() method;
            Decimal value = Decimal.Divide(a1, a2);
  
            // Display the division
            Console.WriteLine("Result of "+
                 "division : {0}", value);
        }
  
        catch (OverflowException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

输出：

Result of division : 2

示例2： OverflowException程序

// C# program to demonstrate the
// Decimal.Divide(Decimal, 
// Decimal) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // Declaring the decimal variables
            Decimal a1 = Decimal.MaxValue;
            Decimal a2 = 0.01m;
  
            // dividing the two Decimal value
            // using Divide() method;
            Decimal value = Decimal.Divide(a1, a2);
  
            // Display the division
            Console.WriteLine("Result of "+
                  "division : {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.Divide(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 the two Decimal value
            // using Divide() method;
            Decimal value = Decimal.Divide(a1, a2);
  
            // Display the division
            Console.WriteLine("Result of"+
                " division : {0}", value);
        }
  
        catch (DivideByZeroException e)
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

输出：

Exception Thrown: System.DivideByZeroException
