As of 2024, Pi has been calculated to over 100 trillion digits! This monumental feat is achieved using advanced algorithms like the Chudnovsky algorithm, which converges rapidly, and the Bailey–Borwein–Plouffe (BBP) formula, which allows for the extraction of individual digits without calculating all preceding digits.

Supercomputers with massive parallel processing power and optimized software libraries (e.g., y-cruncher) handle these calculations. While Raspberry Pi devices cannot compete at this scale, they are excellent platforms for learning and experimenting with smaller-scale Pi computations.

Can calculating all digits of pi be used as a benchmark to test the performance and capabilities of single-board computers like Raspberry Pi?

✅ Absolutely! Calculating Pi digits is a classic benchmarking task for single-board computers (SBCs) like the Raspberry Pi. It stresses CPU performance, memory bandwidth, and thermal management. Many Raspberry Pi users run Pi calculation benchmarks to compare different models (e.g., Raspberry Pi 4 vs. Raspberry Pi 400) or to test cooling solutions.

This benchmarking helps hobbyists and engineers understand the practical limits of their devices and optimize performance for other demanding tasks such as media servers, IoT applications, or lightweight AI workloads.

Are there any practical applications of calculating all digits of pi in fields such as engineering, physics, or computer science, and how can Raspberry Pi be used to explore these applications?

While most practical applications require only a limited number of Pi digits, calculating Pi to high precision has indirect benefits:

  • Engineering & Physics: Precise Pi values improve simulations involving waveforms, fluid dynamics, and structural analysis.
  • Computer Science: Pi calculations test algorithms, numerical stability, and hardware reliability.
  • Cryptography: Randomness properties of Pi digits inspire cryptographic research.
