Hello all,
In the spirit of my last post about flonum-specific math operators,
attached is a patch which implements the following behavior for
Chicken's fxXXX math operators:
I would prefer to keep fixnum ops as they are, since "safe" code might
give still results but will not crash the program (this definition
of "safe"
is used throughout the whole compiler and runtime-system).
What do others say?
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.
cheers,
felix
