- Choose the search view when you know the digits you want to find, or use index view when you know the position.
- Pick a scope first. The page works inside that exact prefix only.
- Copy the selected span after you confirm the range you need.
Classroom presets: start with one short search, then try one index jump before asking students to choose their own range.
The page generates the chosen exact prefix, then searches or jumps inside that scope.
Copy uses this range length. The copied text does not include 3..

How it works
Pi Digit Lab reuses the same exact-computation source as Pi Digits Generator, but this page only shows the current block you are exploring. That keeps the interface focused on find, jump, and copy tasks instead of full-output generation.
Worksheet and investigation prep
- Algebra worksheets
Turn one found sequence or one copied range into a short investigation prompt.
- Graph paper generator
Use it for handwritten notes, range marking, or block-by-block observations during class.
- Quick charts
Summarize match counts or copied ranges in a simple handout chart when needed.
FAQ
Does search work inside the chosen first n digits only?
Yes. If you choose the first 5,000 digits, every search and jump stays inside that exact prefix only.
What does index 1 mean?
Index 1 is the first digit after the decimal point.
Does copy selected range return the whole prefix?
No. It returns only the currently selected span.
What happens if my sequence is not found?
The page keeps the same scope and shows a no-match state so you can change the sequence or the scope.
Where should I go if I need a larger exact output?
Use Pi Digits Generator when you need to generate or export a larger exact prefix.
