;;; Random numbers:

(define (randomize . n)
  (let ((nn (if (null? n)
		(##sys#flo2fix (fp/ (current-seconds) 1000.0)) ; wall clock time
		(car n))))
    (##sys#check-exact nn 'randomize)
    (##core#inline "C_randomize" nn) ) )

(define (random n)
  (##sys#check-exact n 'random)
  (if (eq? n 0)
      0
      (##core#inline "C_random_fixnum" n) ) )
