::mfp::math::stat_stoch::quick_sort(2) :

Function quick_sort(desc, original_list) returns a sorted list of an arbitary number of parameters. If desc is true (or 1), list elements are from largest to smallest, otherwise (desc is false or 0), from smallest to largest. For example, quick_sort(1, [5,6,7,9,4])'s result is [9,7,6,5,4] while quick_sort(0, [5,6,7,9,4]) is [4,5,6,7,9].
