Defining real numbers to exclude incomputable numbers

The real numbers are normally constructed via Dedekind cuts or similar approaches, which result in incomputable numbers: numbers that no finite algorithm can produce to arbitrary precision. This is ...

Is there literature on non-computable numbers that can't be even be identified?

It seems to me that most real numbers can't be calculated by any finite set of instructions, even if we make use of non-computable functions. First, assume that we have an oracle that will provide ...
