The fact that you tell the %d tag to use 2 spaces will not make it truncate the number. It would be a far worse error to truncate the number than to spoilt the formatting. You can try repeated division

Do you want to show the number of 100,000s there are? Or do you want to show the first two digits? Or some other rule?

To put it another way, what would you want to to print for each of these values?

1
12
1278
127894
127894456789

First two digits.

convert it to a string, then take the substring?

First two digits.


So that's first 2 digits regardless of the scale?

1 --> 1
12 --> 12
1278 --> 12
127894 --> 12
127894456789 --> 12

Yes?

Okay, then, as Fred said: convert it to a string, then take the substring

For a 1‑digit number, you would have to pad it with 0s from the left.

That shows why the % tags should not change their argument. You are not printing the value in a different format, but a different value. "to" and "total" are different, real, words.
