I'm not dyslexic but I have trouble looking at big numbers like 10 digits and telling which is bigger. So I Googled and with most GCC versions with a working locale you put something like %'u in a printf. I also saw mention of a SATSEP macro, but I'm not getting anything to work. I know I could write a formatting function, I just wondered if there's an easier way. And I'm counting bytes, not dollars. :)
