Try storing a float but if loosing the precision is an Killing issue then consider storing that as String by calling the method putString

 putString (String key, String value)

and then parse that into a double

Double.parseDouble(myValueAsString);

parseDouble returns double, which can't be used with `putString` – OneCricketeer May 10 '17 at 17:44
