Q:

How do I print a string in emacs elisp without quotation marks? 

In the *scratch* buffer, I enter the following code and run it with Ctrl-J.
(defun tt ()
  (setq t1 1.735)
  (setq t2 3.278)
  (format "Test 1 is %f.\nTest 2 is %f.\n" t1 t2))
tt
(tt)
"Test 1 is 1.735000. 
Test 2 is 3.278000. 
"

How can I make it print this, without the quotation marks? 
Test 1 is 1.735000. 
Test 2 is 3.278000. 

Many thanks for the help! 

A:

With insert:
(insert (tt))

This will also add nil at the end - the result of insert
