Hi, I would like to extract an array of e.g. integers or floats from a string: s = "1234" -> [12,34] s = "12.413.423.7" -> [12.4,13.4,23.7] How can I use unpack for that? What format string do I need for the two examples above? Where can I find more examples of the unpack method, than in the ruby- doc.org? Thanks for your help Daniel
