Hi guys
I want to share that with you. (may be I wrote some errors that you will spot I'm sure).
I wrote two chapters for the next book: float (with the participation of Nicolas Cellier) and internal number representation (two complements and friend).
I wrote that also for myself so that I can forget and just read it again and could say: ok this is that simple.... :)
