Actually, let me say this, as it's more informative and
constructive.

If you need to convert your string to a number, it's best
to do so explicitly. (If you really want to pass a string
into sprintf, %s is the correct modifier.)

Also note that while Integer() doesn't convert the way
you want, to_i does:

    Integer("09")  # error
    "09".to_i      # 9
