Hi everybody, I'm using a 5 digit broker. When I use the function

Print(Low[0])

I see 4 digit, for instance 1.3147.

If I write

string value=DoubleToStr(Low[0],5);

Print(value) ;

Low[0] is 1.31467.

My doubt is: when I write Low[0] in an expert, the returned value is 1.3147 or 1.31467?

Thank you!

From the manual ... (the last line shown is what you need)

void Print(

...)

Prints a message to the experts log. Parameters can be of any type. Amount of passed parameters cannot exceed 64.

Arrays cannot be passed to the Print() function. Arrays should be printed elementwise.

Data of double type are printed with 4 decimal digits after point. To output more precisely, use the DoubleToStr() function.
