Those decimal points are not aligned on my display.

You can probably guess why: I'm using a proportional font, and spaces are 
not as wide as digits.

So, in addition to the algorithmic tips you've gotten, you need to be sure 
you're printing in a monospaced font such as Courier.

If you print in a proportional font, you need to use other means to align 
the decimal points instead of padding with spaces.
