Of course, this kind of tedium is what computers are for.  Care about
it once, and then make one declaration around your whole programe
(with-my-numeric-conventions ....)

Great!  So trust IEEE, and wrap your program with

(with-ieee-numeric-conventions ...)

You haven't said what *wrong* with that?
