Re: Why don't we switch to C like floating pointed arithmetic instead of automatic expansion to reals?

It's the whole point of it.

I'm afraid, I don't understand your implementation. Isn't 
toFloat(x) + toFloat(y) computed in real precision (first 
rounding)? Why doesn't toFloat(toFloat(x) + toFloat(y)) involve 
another rounding?
