Cubase Processing Precision, 32 Bit or 64 Bit?

But I’m talking about the internal precision, 32 or 64 bit float, not the project bit depth.
You told that the first thing Cubase does when playing audio is to convert it to the selected 32 or 64 bit float, then it remains like that for the whole signal chain.

I am asking if the signal remains at 32 or 64 bit float up to the interface, or if it is converted back to the selected project bit depth before going to the interface.

I am asking because I made that post and I want to have additional details because I got told by a user that it was working like this.
