Remarks
Implements the getFloat method as per the specification in Preferences#getFloat(String,float).
This implementation invokes #get(String,String) <tt>get(key, null)</tt>. If the return value is non-null, the implementation attempts to translate it to an float with Float#parseFloat(String). If the attempt succeeds, the return value is returned by this method. Otherwise, def is returned.
