Cordinates transformation and other Geo questiona

Hello !!!

I’m trying to figure out how to handle with geo coordinates.

My first point is I have Latitude and Longitude like this 22.015; 43.0330320

However, sometimes the Lats and Longs comes with the “-” in front (I’m below the Equator) and it seems to be the correct. At least for the Lat.

So, in order to have all the points written in the same way I have to put “-” on all ones, right?

Some advice on how to do that??

Thank you in advance!
