Decimal.Remainder() Method in C#

This method is used to compute the remainder when the division is done between two specified decimal values.

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.

Exceptions:

• DivideByZeroException: This occurs when a2 is zero.
• OverflowException: If the return value is less than MinValue or greater than MaxValue.

Below programs illustrate the use of Decimal.Remainder(Decimal, Decimal) Method:

Example 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);
        }
    }
}

Output:

Remainder is : 0.69

Example 2: For 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);
        }
    }
}

Output:

Exception Thrown: System.OverflowException

Example 3: Program for DivideByZeroException

// 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);
        }
    }
}

Output:

Exception Thrown: System.DivideByZeroException
