By the same reasoning, you could say "never round down to 0%, because 
I want to know when there is no similarity".

You cannot be exact when you have to cut off fractions, so why try for 
_exactly_ one number?

Because completeness is special.

I am not convinced. My vote is still for the _common_ practice of just 
rounding. IOW keep it as is.

As I already hinted at, the common result of comparing two files, as
done by e.g. cmp(1), is one bit that indicates equality.  This
information is lost when using up/down rounding, but it is retained when
rounding down.  It's _not_ common to be unable to determine equality
from the result of a file compare.
