Reintroducing comments, removing misplaced spaces and removing unused variables which have been introduced in you merge!
LCIO stores _ALL_ pixel values as floats - this means there are effectively less than 32bit (23 if I'm not mistaken) for any value. EUTelescope somewhere stated that all such values originate from some sort of digitizing and thus are integer value. Therefore internally they are int/shorts - but when passed from/to LCIO they have to be converted to/from float.
