But that sort of gets an arbitrary root. As pointed out, a kth root has k solutions, just as (1)^.5 = 1 or -1; for square roots of positive numbers we routinely use the positive one, although forgetting about the other one sometimes gets us into trouble. Might picking the real root of a negative number where such exists (odd roots) be just too arbitrary? (Not a rhetorical question.) On the other hand, how hard would it be for SAS Institute to code up a complex arithmetic module?
