If I were you I would do it the way Jesper suggests, but I would
replace it with another term, say num_type.  Then put at the top
something like ttn suggests :-

#define  num_type int;
/* #define num_type double; */

(Or use typedef.)

This allows you to change things easily.  I've often done this in the
past to allow me to experiment with using doubles and floats.

You can replace by using a regular expression -- use `C-M-%'. 

"\<" matches the beginning of a word, and "\>" matches the end of a
word.  So "\<int\>" is the string you want to search for.

hee hee answer:

     #define int double

sometimes i wish there were a C-M-% for days of the week...

You could alternatively M-% " int " RET " double " RET !  [no quotes]
(or maybe M-% "(int " RET "(double " RET !) though this in't the elegant
way.
