Convert Last 2 Digits of a double to zeros

New comment
  
Pair= "EURUSD";

Lev00Ask = NormalizeDouble (MarketInfo(Pair,MODE_ASK),3);
           Print (Pair," Lev00Ask = ", Lev00Ask);

I'm learning to code.

When I execute this code, it gives me "Lev00Ask = 1.133"

I want to convert the result to 1.13300 and use it in my next calculation.

I've not been able to find a way around it.
Any help is appreciated.

  1. Your question makes no sense. A double has infinite digits, always. If you want to see the extra zeros when you print it
    string   price_as_string(double price){return DoubleToString(price, _Digits);     }

  2. You want to use it, just use it.

  3. If you want to convert a price to the lower level:
    Lev00Ask = MathRoundDown(MarketInfo(Pair,MODE_ASK),100*_Point);
double MathNearest(  double v, double to){ return to * MathRound(v / to); }
double MathRoundDown(double v, double to){ return to * MathFloor(v / to); }
double MathRoundUp(  double v, double to){ return to * MathCeil( v / to); }

Thank you for responding.

I created a function to check if a BuyStop order exist at a certain price. If not, it should place an order at that price.

But it always return false. I reckon it's because I'm comparing Lev00Ask 1.133 with OrderOpenPrice() which is 1.13300.

Please see code below

bool BuyStopExistAtLev00()
{    for( int i=OrdersTotal()-1;i>=0;i-- ) {
        if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)
        && OrderSymbol()==Pair 
        && (OrderType()==OP_BUYSTOP || OrderType()==OP_BUY) 
        && OrderOpenPrice()==Lev00Ask)
          return(true); }  
           return (false); }

This is a feature of double. Doubles are rarely equal. You should compare a difference. See the example below.

bool BuyStopExistAtLev00()
{    for( int i=OrdersTotal()-1;i>=0;i-- ) {
        if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)
        && OrderSymbol()==Pair 
        && (OrderType()==OP_BUYSTOP || OrderType()==OP_BUY) 
        && fabs(OrderOpenPrice()-Lev00Ask)<_Point*0.1)
          return(true); }  
           return (false); }
