MicroNMEA converting to N/S/E/W format

Projects Programming

I am trying to convert nmea.getLatitude() to string and add N/S/E/W . However, none of the way of converting long to string works. Any ideas?

  if (nmea.isValid() == true) {
    long latitude_mdeg = (nmea.getLatitude() / 10000., 2);
    long longitude_mdeg = (nmea.getLongitude() / 10000., 2);
    String latitude1_string = String(latitude_mdeg);
    String longitude1_string = String(longitude_mdeg);
    Serial.print("Latitude (deg): ");
    Serial.println(latitude1_string );
    Serial.print("Longitude (deg): ");
    Serial.println(longitude1_string);

}

The problem I have is latitude1_string and longitude1_string prints out "2".
I am not sure why

Get rid of the ", 2" after the decimal places. Look up "C/C++ comma operator" to learn why.

You don't need the String operations. Serial.print() can handle numbers.

I am just printing it out right now for debugging. I still need it in a variable to form other strings.

Ok. Found what's wrong. Thanks

No, you never do.
