So saying that in floating point your position resolution is 2.5m is not quite true... it depends on what value you want to represent...

Sorry: I should have said: If you are at about zero degree lattitude but 179 degrees longitude and you store lattitude and longitude directly into a 4byte IEEE756 floating point representation, then your longitudinal resolution will be only 2.5m.
