I do it this way because I've been doing the same method in BASIC for
years. It works fine.
It also helps for sorting purposes.
by having all the strings the same length helps to guarantee that sorting
will not screw it up.
When the number equals 1,
the first "if" adds a zero.
The second "if" adds another zero because it is less than 10.
numbers between 10 and 100 only get one zero added.
