SQL *is* server. Please begin by having a comment containing a
table for integer type arithmetics, something like this:

  Plus operation:
  --------------
  
               integer   float

  integer      integer   float
  float        float     float

It's best to implement such table in the source code too, and not
have complicated branching.
