Little help regarding concatenate strings

Hi to all,

I have this:

               Serial.print("Latitude= ");
               Serial.print(, 6);
               Serial.print(" Longitude= ");
               Serial.println(gps.location.lng(), 6);

and I need to do this:

      latlon = ( + "," + gps.location.lng(), 2);

How can I do that?

Thank you in advance.

Can you please explain more about what you are trying to do and why?
It looks like you are trying to change the 6 places after dp to 2 and add a comma between the values. What is reading the serial output?

Why not this. It would be unusual for the receiving side to require a concatenated statememnt.

               Serial.print("Latitude= ");
               Serial.print(, 2);
               Serial.print(" Longitude= ");
               Serial.println(gps.location.lng(), 2);

if the line is giving you an error try casting?????

  latlon = (String( + "," + String(gps.location.lng()));

Thank you all for your help
