Do you mean: get-count

The function which does something like this:

;; scale all numbers of lst that the sum of lst is 25
(setf lst '(1 2 3 4 5))
(setf list-sum (sum lst))
(setf scale 25)
(setf result1
(loop for i in lst
      collect (* 1.0 (* scale 
                         (/ i list-sum)))))
;; test (sum result1)
(setf result2
(loop for i in lst
      collect (round
               (* 1.0 (* scale 
                         (/ i list-sum))))))
;; test (sum result2)
