How do I convert an integer to a string?
 for ex:    i  is 3 ...   given i , how do I coerce it to:    "3"

thanks, Rick Pionkowski

According to taste, one of these:

(write-to-string 3 :base 10 :radix nil)

(format nil "~D" 3)

(defun string-value-of (x)
  (princ-to-string x)
)

Although this is heavily used, robust code is better off to use
(WRITE-TO-STRING x :BASE 10 :RADIX NIL)
so that it is insulated from the effects of *PRINT-BASE* and *PRINT-RADIX*.

Using (FORMAT NIL "~D" x) mostly also works but may be a bit more overhead.
