Sure.

If you observe my other comments, you'll see I'm well aware of what the article is about.
You used 13 as an example in a response to my comment that was:
Isn't modulo the same as truncation when dealing with powers of two?
I don't see the number 13 in any of my comments on this thread (except this one, or where I quoted you). Perhaps you are confusing me with someone else?
