Have just finished drawing schematic and wrote a couple of words about hardware. Nothing special, but definitely better than it was.

After:

So, the tutorial is technically finished.

Well, it's not quite a tutorial, I'd say it's a description of internal functioning of the calculator and theory that stands behind all numerical magic. Anyway, it can be useful for anyone who will want to understand floating point and implement such a calculator from scratch. I wish I had such a thing in the beginning of this journey.

Now I'm gonna proofread it and edit, redraw some illustrations, numerate all formulas, etc.

And at the end I'll translate it in English, like it was with code comments.

I guess, by the end of this year century everything will be done.
