Hackers Delight is in the category of books that I’ll always keep positioned prominently on my bookshelf.
Always stings when you’re reading code and it says at the end of the document that it’s non-free.
I have this open in a tab for about a week now, meaning to read it whenever I have time. I am also writing an article about the theorem and the derivation of this algorithm for division (but again, postponing working on this further until I have time).
But yeah, nice algorithm :)
