How to use Find n-th Pi Digit
- 1. Enter the digit position. Type a value into Digit position (after the decimal point) to specify which decimal digit of pi, 3.14159 and so on, you want returned.
- 2. Read the digit. The tool expands pi to sufficient precision and returns the single digit sitting at your requested position after the decimal point.
- 3. Copy the digit. Copy the returned digit into your answer or notes, or change the position field to settle the next argument right away.
When to use Find n-th Pi Digit
Find n-th Pi Digit returns a single digit at a chosen position in pi's decimal expansion without generating the whole constant. It suits Pi Day questions, memorization checks, and number theory lookups.
- Settling a Pi Day trivia bet. A group is arguing over what the 100th digit of pi actually is, and entering the position here settles the debate with a confirmed answer instantly.
- Checking a pi memorization attempt. Someone claims to have memorized pi to 50 digits, and spot-checking a digit at a specific position confirms whether the claim holds up.
- Testing a pi-computation algorithm. You implemented a spigot algorithm or series expansion for pi and want to verify a digit far into the expansion matches the known value.
- Writing a puzzle involving a specific pi digit. A recreational math challenge hinges on the value of one particular digit of pi, and looking it up here gives the exact figure needed for the puzzle.

About the Find n-th Pi Digit tool
Find n-th Pi Digit runs as plain JavaScript in your browser tab, with no server behind it. Calculate specific digits of π. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Math Tools section, 234 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Digit position (after the decimal point) setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
