This will have to include removing +inf.0/-inf.0 in favor of not
overflowing as well, of course.

Yes, the intention is to catch overflow as well, though

infinity is a useful numerical concept and I have no intention

to remove those values.

 

I admit you'd have to be daft to do
scientific work in Chibi without muscular C libraries attached (in the
style of Python), but perhaps there are others who like the delicate yet
performant compromise of IEEE binary representation, so I hope this will
still be a configure-time option.

I think any slow-down is better than giving the wrong answer,

but you will be unlikely to notice a significant drop in performance.
