You already have a double. Why are you posting?

If you want to print it, you need it as a string.

Floating-point has infinite number of decimals, it's your not understanding floating-point and that some numbers can't be represented exactly. (like 1/10.)

Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.

ok i used the doubletostring and yet does not work 

x=Low[iLowest(Symbol(),0,MODE_LOW,8,1)]; 
   xx==Low[1];
  //drawlabel(0,"swing l to be checked1",514,10,CORNER_LEFT_UPPER,StringConcatenate("this is swing low candle "+isthiscandleswingl()+" becaue the curr low is "+xx),15,DarkOrange,true,false); 
  //drawlabel(0,"swing l to be checked2",1300,10,CORNER_LEFT_UPPER,StringConcatenate(" and lowest candle in range of 8 "+x),15,DarkOrange,true,false); 
Print("Lowest of 8 ",x);
Print("Current Low ",DoubleToString(xx,Digits ));
 
You have not used DoubleToString on X
Anyway, what does it mean "does not work"?

You assigned value of XX with == instead of =
== Is a compare operator, not an assignment one.
Look better at the code, it's only 3 rows.
