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.

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))))
