[QUOTE="Christoffer Lernö, post: 4550227"] (-9...10).rand won't give the expected answer. I think the below should fix the problem when the last entry in the range is excluded: class Range def rand return first if exclude_end? && last == first Kernel::rand(last - first + (exclude_end? ? 0 : 1)) + first end end [/QUOTE]
