And that is how we define what is a computable real number. We can compute the approximations. Actually we need also to be able to compute a modulus of convergence, to assure that addition of the computable real numbers is a computable operation. Turing get this wrong in his paper, but corrected this in a footnote in most re-publication of his paper. > but with most of the others you don't even know how to represent them > mathematically and thus haven't a prayer for calculating them. AG Yes, in classical logic/theories, most real numbers are not computable. Note that in intuitionistic mathematics, Brouwer has introduce the axioms that all real numbers are computable, but as I use classical logic, that does not concern us. Yet that play a role in the logic of the subject ([]p & p, S4Grz, …).
