Discussion of the TAKT note The official QuantLib wheel prints different last digits on different Linux systems: https://taktcycles.com/notes/quantlib-glibc-last-digits.html

The same official QuantLib 1.43 wheel prints different last digits on glibc 2.28 than on 2.39 and 2.41, because it calls the system's exp, log and pow.
