Please tell me how to round off a value to 4 decimal places.

I have a calculation like this 

a_M5_461=(Price1_M5_1-4.61*(Price1_M5_1-Price2_M5_1));


where Price1_M5_1 and Price2_M5_1 are values of quotes. However, a_M5_461 is not four decimal places, but more, as long as the expression contains the multiplication by 4.61. We need to make the value be rounded to 4 decimal places.

Please tell me how to do it. I can't find it anywhere.

a_M5_461=NormalizeDouble(Price1_M5_1-4.61*(Price1_M5_1-Price2_M5_1),Digits);
 

Thank you very much. This is the second time you've helped.

Thank you.

Thank you.

Is that all the indicator you're doing. Or is it something else?

I'm doing it. I'm in no hurry. The indicator is complicated, but I'm interested in doing it myself. I like complex tasks.

Your option does not work. When a value is displayed on the screen, 8 decimal places are shown. Of these, 4 are zeros.

NormalizeDouble() is used for calculations, DoubleToStr() is better for output;

Yes. It fits perfectly. Thanks again.

 

Please advise what the error is:


extern int RSI_Periods = 14;
extern int Percent_K   = 14;

// double Buffer1[];
double Buffer1[100000];

start() {

   while( i>=0) {

// ============================================================================================
      double Current_RSI, Lowest_RSI, Highest_RSI;

      Current_RSI    = iRSI(NULL,0, RSI_Periods,PRICE_TYPICAL, i);
      Highest_RSI    = Current_RSI;
      Lowest_RSI     = Current_RSI;

      for(int x= i+1; x<= Percent_K+ i+1; x++){
         Lowest_RSI  = MathMin( Lowest_RSI, iRSI(NULL,0, RSI_Periods,PRICE_TYPICAL, x));
         Highest_RSI = MathMax( Highest_RSI,iRSI(NULL,0, RSI_Periods,PRICE_TYPICAL, x));
      }


      Buffer1[ i]     = (( Current_RSI- Lowest_RSI) / ( Highest_RSI- Lowest_RSI)) * 100;
// ============================================================================================


   Comment(
      "\n",
      "\n", "Buffer1[i+30] = ", Buffer1[ i+30],
      "\n", "Buffer1[i+1] = ", Buffer1[ i+1],
      "\n", "Buffer1[i] = "  , Buffer1[ i],
      "\n",
      "\n"
   );

      i--;
   } // while
}


As a result, Buffer1[i+1] and Buffer1[i+30] show 0 when the Indicator starts.

After some time Buffer1[i+1] starts to show non-zero value (why not immediately?),

but Buffer1[i+30] stays 0.

- What is it related to?

- What does this have to do with it?

And what i equals?
