Line 652:
<lang lisp>(parse-integer "1a" :radix 16) ; returns multiple values: 26, 2
(write-to-string 26 :base 16) ; also "1A"</lang>
Alternative implementation using FORMAT's ~R directive and #nR reader macro
<lang lisp>(defun decimal-to-base-n (number &key (base 16))
(format nil (format nil "~~~dr" base) number))
(defun base-n-to-decimal (number &key (base 16))
(read-from-string (format nil "#~dr~d" base number)))</lang>
