Exactly. An average developer thinks "it's just some large number". A business user needs to read the number and make sense of it. And yes, showing 133,854,113,715,608 doesn't make much more sense (though at least I can compare the numbers between them). In this case you would express it in billions and mention you did it (doesn't matter that the underlying calculation is wrong, that's not even the point, none of the other numbers in the page are formatted in a readable way).
