I think you want:


#+name: my-random-gen
#+header: :var n=0 :var lim=0
#+BEGIN_SRC emacs-lisp
(loop repeat n collect (random* lim))
#+END_SRC

and this various versions of this

#+BEGIN_SRC emacs-lisp :var results=my-random-gen(n=5, lim=1.0)
results
#+END_SRC

#+RESULTS:
| 0.27765703201293945 | 0.7524830102920532 | 0.854852557182312 |
