If you just mean the text content of the buffer you can use

(buffer-substring p1 p2)

or

(buffer-substring-no-properties p1 p2) 

which return the buffer-content between p1 and p2.

HTH Joakim

Untested:
---------

(defun enlarge-double (p1 p2)
  (interactive "r")
  (let  ((new-number    (* 3.456 (string-to-number  (buffer-substring-no-properties p1 p2)))))
     (kill-region p1 p2)
     (goto-char p1)
     (insert (format "%s" new-number))))
