It's probably not related but: this part of `calc-fin-rate' is clearly
suspicious:

      (calc-to-percentage
       (calc-normalize
	(cons (if (calc-is-hyperbolic) 'calcFunc-ratel
		(if (calc-is-hyperbolic) 'calcFunc-rateb ;; !@?!
		  'calcFunc-rate))
	      (calc-top-list-n n))))

Looks like one of those two identical `calc-is-hyperbolic' tests
must be replaced with `calc-is-inverse' (the second one?).


Michael.
