It's nonsense. The reason ju'u is an operator rather than a PA is to allow talking about variable bases: (10 base b) - 1 = 10 base (b - 1), e.g. But the left operand can't be anything but a digit string: (a+b) base c is just nonsense. -- Not to perambulate || John Cowan the corridors || http://www.reutershealth.com during the hours of repose || http://www.ccil.org/~cowan in the boots of ascension. \\ Sign in Austrian ski-resort hotel
