add function to existing numeric text

[windowsxp5]

Hi all,
I am looking for a lisp that can do add function to existing numeric text.
Ie: one of my building drawings I assume ground level 0(zero).now the client came with new surveyed ground level.12.22 .now all my levels want to add 12.22+existing level.
Is there any shortcut/lisp?
thanks in advance
