Yeah As far as saw (looking in the site and gooooogle ) it works in 32bit float, but not a single official response (I mean for steiny) says “32” or “64”
I know the difference is pretty “unhearably” (specially for me 
), but again, when used for mastering can be pretty important or when you want to use Cubase for audio analysis proposes, or software/plugin testing (sometimes I do)
