Czy można sprawdzić, czy liczba obliczalna jest wymierna czy całkowita?
Czy możliwe jest algorytmiczne testowanie, czy liczba obliczalna jest liczbą wymierną czy całkowitą? Innymi słowy, możliwe byłoby dla biblioteki, który implementuje numery obliczalne, aby zapewnić funkcje isIntegerlub isRational? Zgaduję, że nie jest to możliwe i że jest to w jakiś sposób związane...
