I asked MS copilot (chat GPT-4):[/quote]
what are the last 30 digits of pi ? ;-)

Copilot:
The last 30 digits of pi are 3095295560. This was computed in 2022 by Timothy Mullican, who calculated 50 trillion digits of pi using a cloud computing service. The previous record was 31.4 trillion digits, set by Emma Haruka Iwao in 2019.
