   double price=1.01561;
   Print("\n","Start price: ",DoubleToString(price,5));
   for(int i=0;i<10;i++)
     {
      Print("MathCeil(",DoubleToString(price,5),") ->  ",MathCeil(price));
      Print("MathRound(",DoubleToString(price,5),") ->  ",MathRound(price));
      Print("MathFloor(",DoubleToString(price,5),") ->  ",MathFloor(price));
      Print("");
      price+=1.9;
     }
  }

Starting with "price" equal to 1.01561 and then increase it by 1.9 in a loop.

Result:

Start price: 1.01561
MathCeil(1.01561) ->  2.0
