📜 A Journey Through Numbers: The History of Pi Calculation and Modern Computing

a glass filled with liquid sitting on top of a wooden table

The quest for Pi is a story of ever-increasing precision. Ancient civilizations had rough approximations. By the 17th century, mathematicians like Ludolph van Ceulen had manually calculated Pi to 35 decimal places. Fast forward to the 1980s, the era of the supercomputer.

Enter the Cray-2, a machine that was the pinnacle of computing power in its day. In 1986, a Cray-2, weighing 5,500 lbs and costing over $30 million, calculated Pi to a then-record 29.3 million digits in 28 hours. It was a monumental achievement, a testament to the power of these room-sized, liquid-cooled behemoths.

But here’s the kicker, and it’s one of our favorite bits of tech trivia. As one user on the Raspberry Pi forums so brilliantly put it, a humble Raspberry Pi Zero can now perform a similar feat in a fraction of the time. The user’s test showed the Pi Zero calculating 40 million digits in about 30 minutes. Their triumphant conclusion? “The Pi Zero didn’t just beat both these iconic supercomputers it DEMOLISHED them. Bambi CRUSHES Godzilla !”

This incredible leap isn’t just about hardware getting smaller and faster; it’s also about the evolution of software and algorithms, a point we’ll explore next.

🥧 Raspberry Pi Models: From Zero to Hero (and Beyond!)

We’ve put together a handy table to compare the most common Raspberry Pi models for this specific task. Think of it as a guide to choosing your champion for the Pi-calculating Olympics. This is a key part of our Electronic Component Reviews.

Raspberry Pi Model CPU (Processor) RAM Options Pi Calculation Suitability (1-10) Why Pi™’s Take
Raspberry Pi 5 Quad-core Cortex-A76 @ 2.4GHz 4GB, 8GB 🏆 10/10 The undisputed champion. Its powerful CPU and fast RAM make it the Usain Bolt of the Pi world for this task. Expect blazing-fast results.

💾 Hardware Requirements: RAM, CPU, and Storage Considerations

  • CPU (Central Processing Unit): This is the brain of the operation. A faster clock speed and more cores (especially with multi-threaded programs) will directly translate to faster calculations. The jump from the Pi 4’s Cortex-A72 to the Pi 5’s Cortex-A76 was a significant leap in performance.
  • RAM (Random Access Memory): Think of RAM as your workspace. Calculating millions of digits requires holding a lot of numbers in memory simultaneously. While 512MB on a Pi Zero is workable, having 4GB or 8GB on a Pi 4 or 5 provides a much larger and faster workspace, preventing the system from slowing down by using the SD card as “swap” memory.
  • Storage: You’ll need a place to store the final result—a text file with a million digits is about 1MB, which is tiny. However, the speed of your storage (a high-quality SD card or even an external SSD) matters for booting the OS and for any swap file usage, which can impact overall performance.

🧠 The Brains Behind the Beauty: Understanding Pi Calculation Algorithms

Video: How is pi calculated to trillions of digits?

Having a fast car is great, but you also need a skilled driver and a good map. In our case, the “map” is the algorithm. The efficiency of your chosen algorithm will have a colossal impact on your success.

🐢 The Leibniz Series: Simple, Elegant, and Painfully Slow

One of the most famous and simplest ways to calculate Pi is the Madhava-Leibniz series: π/4 = 1 – 1/3 + 1/5 – 1/7 + … It’s beautiful in its simplicity and easy to code. However, as noted in the featured video, this formula “converges extremely slowly.” How slowly? To get just 10 correct decimal places, you would need to calculate five billion terms! While it’s a great educational tool, it’s not the right choice for our million-digit quest.

🚀 Machin-like Formulas: A Leap Towards Efficiency

Centuries ago, mathematicians realized they could do better. John Machin developed a formula in 1706 that converges much, much faster: π/4 = 4 * arctan(1/5) – arctan(1/239). Formulas of this type, known as Machin-like formulas, were the standard for high-precision calculations for a long time and are a huge improvement over the Leibniz series. One forum user correctly pointed out that “there are many algorithms that will give you PI which converge faster than 4 * atan(1)”. [cite]

⚡ The Chudnovsky Algorithm: The Modern Pi Powerhouse

Published in 1988 by the Chudnovsky brothers, this algorithm is the undisputed king for calculating Pi to a massive number of digits. It is incredibly efficient, adding about 14 digits of precision for every term calculated. This is the algorithm used in the gmp-chudnovsky.c program that achieved the “Bambi vs. Godzilla” result and is the basis for modern world-record calculations, including the recent computation of 100 trillion digits on Google Cloud. For our million-digit goal, this is the weapon of choice.

🛠️ Gearing Up: Software Tools and Programming Languages for Your Pi Quest

Now that we understand the hardware and the algorithms, let’s pick our tools. Your choice of programming language and libraries will determine the balance between ease of use and raw performance. This is where Microcontroller Programming skills come in handy!

🐍 Python with mpmath: The Friendly Giant for High Precision

Python is famous for being user-friendly, and calculating Pi is no exception. While the standard math module has limited precision, the mpmath library is designed for arbitrary-precision floating-point arithmetic. It’s as simple as setting your desired number of decimal places and asking for Pi.

  • Pros: ✅ Incredibly easy to write and understand.
  • Cons: ❌ Slower than compiled languages like C/C++.

As one Stack Overflow discussion highlighted, even within Python, different algorithms can have vastly different speeds. [cite] But for a straightforward approach, mpmath is a fantastic starting point.

🏎️ C/C++ with GMP: Unleashing Raw Computational Horsepower

When speed is all that matters, you turn to C/C++ and the GNU Multiple Precision Arithmetic Library (GMP). GMP is a highly optimized library for doing math with numbers that are far too large to fit into standard data types. It’s the engine under the hood of the gmp-chudnovsky.c program. As the featured video explains, libraries like GMP are essential for handling the “arbitrary precision arithmetic” needed for this task. [cite]

  • Pros: ✅ The fastest possible performance on your Raspberry Pi.
  • Cons: ❌ Requires compiling code and has a steeper learning curve than Python.

🐧 The bc Command: Your Linux Shell’s Secret Weapon

Don’t want to write any code? Linux has you covered. The bc (basic calculator) command is an arbitrary-precision calculator that lives in your terminal. By starting it with the math library (-l flag), you can use the arctangent function to calculate Pi to a specified number of decimal places.

  • Pros: ✅ No programming required; built into Raspberry Pi OS.
  • Cons: ❌ Not as fast as a dedicated, compiled C program for a very large number of digits.

🏆 The Grand Pi Experiment: Step-by-Step Guides to Million-Digit Glory

Video: PI app- the “manly” way to compare phone speed and power.

Enough talk! Let’s get our hands dirty and start calculating. Here are four methods, from easiest to most powerful.

1. 💨 Method 1: bc – Quick Pi on the Command Line

This is the fastest way to see a lot of digits without writing a single line of code.

  1. Open a Terminal window on your Raspberry Pi.

  2. Type the following command and press Enter. This command tells bc to set the scale (number of decimal places) to 1,000,000 and then calculate 4 times the arctangent of 1, which is Pi. We’ll pipe the output to a file named pi_bc.txt.

    time echo "scale=1000000; 4*a(1)" | bc -l > pi_bc.txt

  3. The time command will measure how long the process takes. Be patient, this will take a while!

2. ✨ Method 2: Python mpmath – User-Friendly Precision

This method is perfect for those who prefer a simple script.

  1. First, install the mpmath library. Open a Terminal and run: 
    pip install mpmath
  2. Create a new Python file, let’s call it calc_pi.py: 
    nano calc_pi.py
  3. Paste in the following code. It sets the decimal places (dps) to one million, prints Pi, and saves it to a file. 
    import mpmath import time start_time = time.time() # Set the desired number of decimal places mpmath.mp.dps = 1000000 # Calculate Pi pi_value = mpmath.mp.pi # Save to file with open("pi_python.txt", "w") as f: f.write(str(pi_value)) end_time = time.time() print(f"Calculation complete!") print(f"Time taken: {end_time - start_time:.2f} seconds")
  4. Save the file (Ctrl+O, Enter) and exit (Ctrl+X).
  5. Run the script from the terminal: 
    python calc_pi.py

3. 🥇 Method 3: C/C++ with GMP – The Performance Champion

Ready for maximum speed? This method uses the same C program and GMP library that crushed the 1980s supercomputers.

  1. Install GMP Development Libraries: This is essential for compiling the code. 
    sudo apt-get update sudo apt-get install libgmp-dev
  2. Download the Pi Calculation Program: This program implements the super-efficient Chudnovsky algorithm. 
    wget https://gmplib.org/pi/gmp-chudnovsky.c
  3. Compile the Program: This command compiles the C code, linking it against the GMP and math libraries. 
    gcc -O2 -Wall -o gmp-chudnovsky gmp-chudnovsky.c -lgmp -lm
  4. Run the Calculation: The first number is the number of digits (1,000,000), and the second is the number of threads (use 1 for single-core Pis like the Zero, or 4 for quad-core Pis like the 4 and 5). We’ll use time to measure and redirect the output to pi_gmp.txt. 
    time ./gmp-chudnovsky 1000000 4 > pi_gmp.txt

4. 🌟 Method 4: The Chudnovsky Algorithm – For the Truly Ambitious

Wait, isn’t this the same as Method 3? Yes! The C program gmp-chudnovsky.c is a direct implementation of the Chudnovsky algorithm. By completing Method 3, you are already using the fastest and most powerful algorithm discussed here, putting your Raspberry Pi in the same league as record-breaking computational efforts.

⏱️ Benchmarking Your Pi: How Fast Can Your Raspberry Pi Crunch Numbers?

Video: The Easiest Way to Calculate Pi.

Running the calculation is one thing, but understanding what’s happening under the hood is where the real learning happens.

🔥 CPU Utilization: Pushing the Core to its Limits

While your calculation is running, open a second Terminal window and install htop, a fantastic system monitor:

sudo apt-get install htop htop

You’ll see a bar for each of your CPU cores. If you’re running a multi-threaded program like the C/GMP version with 4 threads, you should see all four bars pegged at or near 100%. This is a great way to visually confirm you’re using all the power your Pi has to offer, a concept mentioned in the featured video on multithreading. [cite]

💧 Memory Footprint: Don’t Let Your RAM Run Dry!

htop will also show you your memory (Mem) usage. Calculating a million digits requires a decent amount of RAM. If you see your memory usage getting close to the maximum and your swap usage (Swp) starting to climb, it means your Pi is using the slower SD card as extra memory, which will significantly slow down the calculation.

🏁 Time to Completion: The Ultimate Speed Test

The time command we used in the examples is the ultimate arbiter of performance. It will output three values:

  • real: The total wall-clock time from start to finish.
  • user: The total CPU time spent in user-mode code.
  • sys: The total CPU time spent in kernel-mode code.

For our purposes, real time is the number to beat! Challenge your friends, try different Pi models, and see who can get the fastest time.

⚡ Overclocking Your Raspberry Pi: Squeezing Out Every Ounce of Performance

Video: Mile of Pi – Numberphile.

If you’re a true performance enthusiast, you might be tempted to overclock your Pi. Overclocking means running the processor at a higher speed than its default setting. It’s a way to get a “free” performance upgrade, but it’s not without its risks.

⚖️ Risks vs. Rewards: Is the Extra Speed Worth It?

  • Reward: ✅ Faster calculations! A typical overclock might boost a Pi 5’s CPU from 2.4 GHz to 3.0 GHz, which will noticeably reduce your Pi-crunching time.
  • Risk: ❌ Heat and Instability. Pushing the CPU harder generates more heat. Without proper cooling, your Pi will overheat and “throttle” (slow itself down to prevent damage), or even crash. Aggressive overclocking can also lead to system instability and data corruption.

✅ Safe Overclocking Practices for Longevity

  1. COOLING IS NON-NEGOTIABLE: Do not attempt to overclock without a good cooling solution. A simple heatsink is a start, but an active cooler with a fan, like the official Raspberry Pi 5 Active Cooler, is highly recommended.
  2. Edit config.txt: Overclocking settings are managed in the /boot/firmware/config.txt file (for Pi 5) or /boot/config.txt (for older models). You’ll need to open it with sudo nano.
  3. Increase Incrementally: Don’t jump to the maximum possible speed. Increase the arm_freq value in small steps, rebooting and testing for stability each time.
  4. Monitor Temperature: Use the command vcgencmd measure_temp to keep an eye on your CPU temperature. Try to keep it below 80°C.

🗄️ Storing the Infinite: Where Do a Million Digits of Pi Reside?

Video: How Many Digits of Pi Do We Really Need?

You’ve done it! You’ve calculated a million digits. Now what? The result is sitting in a text file. While a million digits sounds like a lot, in computer terms, it’s quite manageable.

🚀 SD Card vs. SSD: Speed and Durability for Your Pi Data

  • Micro SD Card: The standard for Raspberry Pi. A good quality, high-speed card like a SanDisk Extreme is perfectly fine for this project.
  • External SSD: If you’re using your Pi for more intensive tasks, booting from an external SSD can provide a significant speed and reliability boost, especially if the system needs to use swap space.

📄 File Formats and Compression: Making Sense of the Digits

A plain text file (.txt) is the simplest way to store your digits. Each digit (0-9) and the decimal point will take up one byte of space. So, a million digits will be roughly 1MB.

For fun, you can see how well it compresses. Right-click the file and choose to create a .zip or .gz archive. Because the digits of Pi are statistically random, it won’t compress very much, unlike a repetitive text file. This is a neat, practical demonstration of randomness! While world-record calculations use special compressed formats to save space, for our purposes, a simple text file is perfect.

🌌 Beyond a Million: What’s Next in Your Pi-Powered Computational Journey?

Video: Calculating pi to ten decimal places with Machin’s formula.

Congratulations, you’ve successfully turned your Raspberry Pi into a high-precision mathematical instrument! You’ve benchmarked its performance, wrestled with algorithms, and now you have a million digits of Pi to call your own.

But why stop there?

  • Go for 10 million! How long will that take?
  • Explore other constants: Try calculating e (Euler’s number) or the golden ratio (phi) to high precision.
  • Visualize the digits: Write a program to search for your birthday within the digits of Pi or turn the digits into a colorful piece of art.

This project is a gateway to the fascinating world of computational mathematics and a perfect example of what’s possible with DIY Electronics. The only limit is your curiosity.

🚧 Common Pitfalls and Troubleshooting: When Your Pi Gets Puzzled

Even the best of us hit a snag. Here are some common issues and how to solve them:

  • Problem: Command not found when trying to compile the C program.
    • Solution: Make sure you’ve installed the necessary development tools. Run sudo apt-get install build-essential and sudo apt-get install libgmp-dev.
  • Problem: The calculation is taking forever on a Pi Zero.
    • Solution: Patience! The Pi Zero is much less powerful. Check htop to ensure the process is actually running and not stalled. For a faster experience, try a more powerful Pi model.
  • Problem: My Raspberry Pi keeps crashing or freezing during the calculation.
    • Solution: This is almost always due to overheating or an unstable overclock.
      1. Check your cooling. Is the fan running? Is there good airflow?
      2. If you’re overclocking, reduce the arm_freq in your config.txt to a more stable value.
      3. Ensure you are using the official, correct power supply for your Raspberry Pi model. Insufficient power can cause instability under heavy load.
  • Problem: The Python script gives a ModuleNotFoundError.
    • Solution: Make sure you’ve installed the mpmath library correctly. Run pip install mpmath again to be sure.
