Computable numbers are the real numbers that can be computed to within any desired precision by a finite, terminating algorithm. This means that in this context of analysis a computable function should be an algorithm that successively reads in natural numbers from a possibly infinite list specifying an input to ever higher accuracy and accordingly outputs a result as incrementally as an infinite list.

A computable function is often taken to be one that acts on the naalysis numbers a partial recursive function? They are also known as the recursive numbers or the computable reals.

Kleene’s second partial combinatory algebra. See the history of this page for a list of all contributions to it. Every computable real function is continuous Weihrauchp.

Mathematically this is captured by continuous functions on quotient spaces of Baire space computability and goes by the name Type Two Theory of Effectivity or similar. From Wikipedia, the free encyclopedia. The computable real numbers form a real closed field Weihrauchp. The composition of computable real functions is again computable. The field is closely related to constructive analysis and numerical analysis.
