I do have a multi-chapter series on constant-time integer arithmetic -- indeed tagged incl. "bitcoin", as it is meant to be used in (among other places) a rework of the client.

You evidently spent at most 3 seconds reading the link; wouldn't kill you to spend 5 seconds and see what is behind the tag.
