I could have been much clearer, but I am asking something different: if the algorithm is outputting all real numbers between [0,1], (or [0,10] etc. take your pick) then how can some/most of these be called "non-computable"?

I don't see any "algorithm", I see a messy drawing in a notebook, like
something Vi Hart might draw in one of her Youtubes.
