How to convert data received via modbus?

Question

I am getting data in my console program on C# with library Nmodbus4 from a device via modbus rtu. Format: 32 bit with floating point. My answer is 17445. But the expected value is 660.

How to convert the data and get 660 from 17445?

A little explanation would be nice!

namespace Elemer19
{ 
    class Program
    {
        static void Main(string[] args)
        {  
            string[] pathFolder = ReadDirectory.readDir();
            Console.WriteLine("OPENING COM PORT - {0}", pathFolder[0]);

            byte slaveID = 4;
            ushort startAddress = 0x20c;
            ushort numOfPoints =  1;

            SerialPort _serialPort = new SerialPort(pathFolder[0],
                             9600,
                             Parity.None,
                             8,
                             StopBits.One);  
            try
            { 
                _serialPort.Open();

                ModbusSerialMaster master = ModbusSerialMaster.CreateRtu(
                    _serialPort);
                master.Transport.ReadTimeout = 300;
 
             ushort[] data = master.ReadHoldingRegisters(slaveID, startAddress, numOfPoints);
                    
                foreach (int item in data)
                {
                    Console.Write("\r\n{0}", item);  // 17445
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(DateTime.Now.ToString() + ":Connect process " + ex.StackTrace +
               "==>" + ex.Message);
            }
 
            Console.ReadLine();
 
        }
    }}

I found what I was looking for.

            ushort[] received = new ushort[] { data[1], data[0] };
            byte[] asByte = new byte[4];
            Buffer.BlockCopy(received, 0, asByte, 0, 4);
            float result = BitConverter.ToSingle(asByte, 0); 
            Console.Write("Result-{0}", result);   // 660
