How to cut the last decimals?

New comment
 

Hi,

I use an alert-message containing Close[0] and the price shown in the alert window is displayed like this: 1.34420000 (EURUSD) or 134.25000000 (EURJPY).

Can someone please tell me how to cut the last zeros? I didn't find anything with the search function.

Thank you!

You are using + to concatenate the strings, in addition use DoubleToStr() and specify the number of digits you want.
 
Great, it works. Thank you!!

  1. You are using
    Alert( "string"+Close[0] );
    If you use separate arguments you'll get only 4 digits (1.3442 1.34.2500)
    Alert( "string", Close[0] );
    Instead, format the number to correct number of digits (1.34420 or 134.250 on a 5 digit broker)
    string   PriceToStr(double p){   return( DoubleToStr(p, Digits) );            }
:
   Alert( "string"+PriceToStr(Close[0]) );
  2. By your post, you really don't want to cut ALL the "last zeros" (1.35000 -> 1.35) but should you really mean that: Alert( "string", DoubleToString(Close[0]) );
    string   DoubleToString(double v, int d=8){              // 1.60000000 -> 1.6
   string   value = DoubleToStr(v, d);
   for(int iRight = StringLen(value)-1; true; iRight--){
      int      c = StringGetChar(value, iRight);
      if(c != '0'){
         if(c == '.') iRight--;
         break;
      }
   }
   return( StringSubstr(value, 0, iRight+1) );
}
string   SDoubleToStr(double v, int d, string s="+"){       if (v < 0.) s = "";
                                             return( s + DoubleToStr(v, d) ); }
string   SDoubleToString(double v, string s="+", int d=8){  if (v < 0.) s = "";
                                          return( s + DoubleToString(v, d) ); }
