Just as a sidenote to the help provided by others: In some cases, the usual rounding of a ending 5 upwards (3.5 => 4, 3.45 => 3.5 etc.) can give an unwanted systematic bias to data. In those cases, a rounding up- or downwards with a probability of 0.5 each can be appropriate, f.e. 3.45 => sometimes 3.4, sometimes 3.5 joe -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
