Well, AIUI it was supposed to be a mathematical example, not a code snippet, but apart from that — yes, indeed. Of course unless x happens to be of floating point type, and n != 0. But then the results for n < -1 or n > 1 would presumably come as a surprise to a considerable number of people. :) Regards Urban -- DNG - we split your hairs at the subatomic scale. 8^) _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
