Comment (by eschnett):

 As much as I dislike the sign convention for %, I think it is important to
 be consistent with C (and Fortran), and to be consistent between / and %.

 Here is an idea:
 - define a function CCTK_INT imod(CCTK_INT, CCTK_INT) that wraps %
 - define a macro isint(T) ((T)0.1==(T)0.0)
 - use isint(x) ? imod(x,y) : fmod(x,y)
