The following program explains how to remove the trailing zeros in a decimal type.
Also, it is doing the rounding operation also.

Example:
The following code will remove the trailing zeros as well as rounding the input with four characters after the decimal point.

using System;
using System.Text;

namespace forgetCode
{

   class program
    {        
        public static void Main()
        {
            decimal[] decimalNumbers = { 1.0M, 1.01M, 1.0010M, 0.00M, 1.0050M ,5.001000M,6.12347654333M};

            foreach (decimal decimalNumber in decimalNumbers)
            {
                Console.WriteLine("Original Decimal Number = {0}, Without Zeros = {1}",
                                    decimalNumber, decimalNumber.ToString("0.####"));
            }
        }
    }
}

Output:
Original Decimal Number = 1.0, Without Zeros = 1
Original Decimal Number = 1.01, Without Zeros = 1.01
Original Decimal Number = 1.0010, Without Zeros = 1.001
Original Decimal Number = 0.00, Without Zeros = 0
Original Decimal Number = 1.0050, Without Zeros = 1.005
Original Decimal Number = 5.001000, Without Zeros = 5.001
Original Decimal Number = 6.12347654333, Without Zeros = 6.1235
