using sstream

[noshkren]

I am new to sstream. I am also trying to convert a double to a string. I need a set precision of 3 so that is why I need to use it. I've tried a bunch of different way to set this up, so now I am turning to here for help.

double formatPoint(double x, double y, string format) {
	stringstream stream;
	stream << fixed << setprecision(3)<<"("<<x<<","<<y<<")";
	string format = stream.str();

	return format;
}

Hello noshkren,

It would be a good idea to edit your OP and remove the green check that tells everyone that you have your answer.

You almost have it right.

Try this:

std::string formatPoint(double x, double y)
{
	std::stringstream stream;
	stream << std::fixed << std::setprecision(3) << "(" << x << ", " << y << ")";
	std::string format = stream.str();

	return format;
}

I changed the return type and removed the third parameter.

Another option:

void formatPoint(double x, double y, std::string& format)  // <--- string passed by reference.
{
	std::stringstream stream;
	stream << std::fixed << std::setprecision(3) << "(" << x << ", " << y << ")";
	format = stream.str();  // <--- Removed type specifier.
}

Hope that helps,

Andy
