%s will be the placeholder for a string and %d for a number. If you used
say 15 as the value, and the template is %s you will get 15.to_s and is the
value was "15" and the template was %d, the value will be "15".to_i. In
other words it will try to do the appropriate conversion. So given your
example it worked. But let's say your template was %d, if you pass as a
value 15 or "15" that would work, but "fifteen" will throw an error. %s
will work, in all cases, but may not be what you want.
