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.
