[QUOTE="Robert Klemme, post: 4446002"] *Hands over some cooling ice* :-) The difference in efficiency is one issue. But there is a conceptual difference: it depends whether you want to align printed output or round a numeric value in a calculation. For the first task sprintf is probably better because the amount of places printed is guaranteed (by the format string), while it's not if you just round the number and print it. Kind regards robert [/QUOTE]
