The people I know will expect "100% identical" or even "100.0% 
identical" to mean identical, period.  They will be quite surprised to 
hear that "99.95%" is supposed to be included.

Granted, 100.0% means as close as you can get to "completely" with 4 
digits. But if you have an integer, you better use the complete range, 
rather than arbitrarily make one number more important than others.

For if you see an integer, you usually assume a rounded value. If you 
don't, you're hopeless.

Why hopeless?  It's a useful convention to define "100%" as "complete
(not rounded)".

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?

Ciao,
