I think the fx* shouldn't check their arguments, ever. While the safe/ 
unsafe rational makes sense (nicely symmetric), people shouldn't use  
these routines if  not 100% sure of the types. The goes for the  
(fixnum arithmetic) declaration.

The fp* routines must accept fixnums so checking is necessary for  
those, otherwise it should just assume an fp value.

I agree w/ the flonum? & x/0 -> inf, etc., though. Thank you Mr. Farr.
