Carl Witthoft's serendipitous discovery is a nice example of how secrets can be guessed by wondering "what if ... ?". So probably you don;t need to tell the secrets. Taking the "negative digits" to their logical extreme: round(654.321,2) # [1] 654.32 round(654.321,1) # [1] 654.3 round(654.321,0) # [1] 654 round(654.321,-1) # [1] 650 round(654.321,-2) # [1] 700 round(654.321,-3) # [1] 1000 round(654.321,-4) # [1] 0 which is what you'd logically expect (but is it what you would intuitively expect?).
