Calculate π to arbitrary decimal precision in your browser.

FAQ

How many digits can I compute?

The practical limit depends on your device. Most browsers can handle 10,000–100,000 digits comfortably. Beyond 500,000 digits, memory usage becomes significant.

Why is consecutive mode slower?

The spigot algorithm generates digits one at a time. Searching for consecutive patterns may require computing many digits before a match is found.

Why can't I use multi-threading in consecutive mode?

Consecutive digit detection requires sequential digit generation. Multi-threaded mode uses parallel Machin formula summation, which computes all digits at once after aggregation.

Is the result accurate?

Yes. The spigot algorithm is mathematically exact. Multi-threaded Machin mode uses BigInt arithmetic for arbitrary precision.

Does the best result reset?

The best result persists in local storage until you clear browser data. It only updates when a new computation produces more decimal places.

Can I use this offline?

Yes. Once the page is loaded, no network connection is needed.
