format ~9,2$ gives inconsistent results.

[pjb@…]

A funny bug with ~$ formating:

(defparameter *inflation*      1.06)
(defparameter *duration*      15          "Year")
(defparameter *yearly-amount* (* 12 1200) "Euro")
(defparameter *now-a-year*    (nth-value 5 (decode-universal-time (get-universal-time))))

(defun plus-interest (amount year rate)
  (* amount (expt year rate)))

(with-standard-io-syntax
 (loop
   :for i :from 15 :downto 0
   :for that-year-amount = (plus-interest *yearly-amount* i *inflation*)
   :sum that-year-amount :into total
   :do (format t "~4D:   ~2,9$   ~2,9$~%" (+ *now-a-year* i) that-year-amount total)))
