Rounding in mql4

double value=0.9731300000000001;
double value2=NormalizeDouble(value,Digits);
Print(value2);

double Yuvarla(double Sayi)
{
double _sayi1=MathRound(Sayi*MathPow(10,Digits));
double _sayi2=_sayi1/MathPow(10,Rakam);
return _sayi2;
}

Used in mql4 language NormalizeDouble() function sometimes does not work properly. You can see in the example below. double value=0.9731300000000001; double value2=NormalizeDouble(value,Digits); Print(value2); As a result, although I want to get the result of 0.97313, the result is 0.9731300000000001. How can I fix. double Yuvarla(double Sayi) { double _sayi1=MathRound(Sayi*MathPow(10,Digits)); double _sayi2=_sayi1/MathPow(10,Rakam); return _sayi2; } this method didn't work either

   double value=0.9731300000000001;
   string value2=DoubleToString(value,Digits);
   double value3 = StringToDouble(value2);
   Print(value3);

Check the documentation on NormalizeDouble at: https://docs.mql4.com/convert/normalizedouble Please note that when output to Journal using the Print() function, a normalized number may contain a greater number of decimal places than you expect. For example, for: double a=76.671; // A normalized number with three decimal places Print("Print(76.671)=",a); // Output as is Print("DoubleToString(a,8)=",DoubleToString(a,8)); // Output with a preset accuracy you will have the following in the terminal: DoubleToString(a,8)=76.67100000 Print(76.671)=76.67100000000001...
