How is this error possible?

[[Deleted]]

I'm absolutely stunned by the behaviour of my EA during strategy testing. Why in the world are there two different outputs. How could Ask be perfectly divisible by CurrentProfitTarget and not equal to CurrentProfitTarget? Here is the relevant code:

Print("LookForClose()");
Print("Ask/CurrentProfitTarget: ", Ask/CurrentProfitTarget);
Print("Ask*10000: ", Ask*10000000, " CurrentProfitTarget*10000000 ", CurrentProfitTarget*10000000);
Print("Bid: ", Bid, " Ask: ", Ask, " TradeDirection: ", TradeDirection, " CurrentProfitTarget: ",

CurrentProfitTarget, " ProfitTargetFlag: ", ProfitTargetFlag);
if(ProfitTargetFlag == 0)
{ if(TradeDirection == "DOWN")
Print("First part matches");
if(Ask == CurrentProfitTarget)
Print("Second part matches");
if(TradeDirection == "UP" && Bid == CurrentProfitTarget)
ProfitTargetFlag = 1;
if(TradeDirection == "DOWN" && Ask == CurrentProfitTarget)
ProfitTargetFlag = 1;
if(ProfitTargetFlag == 1)
Print("Profit Target has been reached.");
}

Relevant Output 1:

Uninstalling and reinstalling MetaTrader seems to resolve this problem.
