When using variables instead of values, coding doesn't work!!

In this code snippet, Instead of BuyLots*1, BuyLots*3,BuyLots*9, if i use digits like 0.1,0.3,0.9 respectively. The code works, if not the the below code does not work. can anyone point out what wrong i have done in this code??



   extern double SellLots = 0.1;
   extern double BuyLots = 0.1;
 

 
    bool exists3 = false;
    bool exists4 = false;
    bool exists5 = false;
    bool exists6 = false;
    for (int i=OrdersTotal()-1; i >= 0; i--)
    if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES))
    {
        if (OrderType() == OP_BUY && OrderSymbol() == Symbol() && OrderMagicNumber() == 1)
        {
            exists3 = true;
        }
        if (OrderType() == OP_SELLSTOP && OrderLots() ==SellLots*1 && OrderSymbol() == Symbol() && OrderMagicNumber() == 1)
        {
            exists4 = true;
        }
         if (OrderType() == OP_SELLSTOP && OrderLots() ==SellLots*9 && OrderSymbol() == Symbol() && OrderMagicNumber() == 1)
        {
            exists5 = true;
        }
          if (OrderType() == OP_SELLSTOP && OrderLots() ==SellLots*27 && OrderSymbol() == Symbol() && OrderMagicNumber() == 1)
        {
            exists6 = true;
        }
    }
  
    
     if (exists3 && OrderLots() == BuyLots*1 && exists4)
    {
        DeletePendingOrder();
        SellPendingOrder(SellLots*3,SellTakeprofit*2);
    }   
      else if(exists3 && OrderLots() == BuyLots*3 && !exists5)
   
    {
      SellPendingOrder(SellLots*9,SellTakeprofit*3);  
        
    }
      else if(exists3 && OrderLots() == BuyLots*9 && !exists6)
   
    {
      SellPendingOrder(SellLots*27,SellTakeprofit*4);  
        
    }

Read the threads, there are many options to correctly compare double variables/values.
 
hmmm, i got an alternative idea for that and now is working...i converted them to integer by multiplying them with some 100s, and stored in integer variables, then compared them.... thanks dudes..
