 Much easier to figure out, don’t you think?

Try 20 * BILLION; it will overflow if not careful.
I'd normally write '20 billion' outside of C, since I use such numbers, with lots of zeros, constantly when writing test code.
But when it isn't all zeros, or the base isn't 10, then numeric separators are better.
