It's not a bug. It has nothing to do with round(), it is the way R prints numbers by default. If you ask to print 0.90, you'll get [1] 0.9 because 0.9 and 0.90 are the same number. If you want trailing zeros to print, you need to specify a format to do that, e.g. > noquote(format(0.9, nsmall=2)) [1] 0.90 The noquote stops the "" from printing. You could also use sprintf() or formatC() for more C-like format specifications.
