Hear, hear!  Average function using arithmetic mean  (using proposed math.sum function) function math.avg(...) return math.sum(...) / select("#",...) endOn a side note, I find it vaguely disappointing how many (too quick) responses to the original post were utterly wrong given the sample results. I know (hope?) we all could do better given some real effort. This seems to be a bit of a trend lately  of shooting from the hip with solution/sample code. Perhaps we should be less quick to respond and more careful with such responses?
