Why is this a bug? If you take apply floor to a number that you expect to be exactly 3, but compute it on a binary computer via logs to base e, you must expect some rounding error.
BTW, on my Windows XP machine I do get > floor(log10(1000)) [1] 3 There is no bug in R, but your usage of it is potentially dangerous. You might want to ensure your R is up-to-date: version 1.7.1 is current.
