So, I updated the main post with some "findings" from this thread.
As I stated: arbitrary and meaningless? Indicative of a larger design? You decide!
... and you still got it wrong. You cannot divide a whole number by 10 or more and expect the result to have the same number of digits.
If you divide 10 (2 digits) by 10, you get 1 ( 1 digit).
If you divide 100 (3 digits) by 10, you get 10 (two digits)
If you divide 1000 (4 digits) by 10, you get 100 (three digits)
So, if you divide 1911251893 by 11, the number you get is 1737501719.37 (rounded), not 17375017193.37 (rounded, again)
