i would take a wild guess and say that hexadecimal value of 0 and decimal value of 0 are interchangeable.
as to why we have to change it then, i dunno.
if you want to open the window you hover over, try option 1.
and, as to why your wallpaper disappeared, i haven't the slightest idea
mine was 0 already as well, actually.
