How to use Find n-th e Digit
- 1. Enter the digit position. Type a value into Digit position (after the decimal point) to specify which decimal digit of Euler's number, e, 2.71828 and so on, you want returned.
- 2. Read the digit. The tool expands e 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 look up another digit right away.
When to use Find n-th e Digit
Find n-th e Digit returns a single digit at a chosen position in the decimal expansion of Euler's number without expanding the whole constant yourself. Use it for number theory problems or checking a hand calculation.
- Answering a specific-digit puzzle. A math puzzle asks for the 30th digit of e rather than the whole expansion, and entering the position gets you the exact answer without listing dozens of digits.
- Checking a memorized expansion. You memorized several digits of e for a competition and want to confirm one specific digit at a chosen position matches the true expansion.
- Verifying a high-precision arithmetic library. You are testing a library that computes e to arbitrary precision and want to spot-check a digit far into the expansion against a trusted source.
- Building a trivia or puzzle answer key. You are preparing a question about e's decimal expansion and need a confirmed digit at a specific position before publishing the answer.

About the Find n-th e Digit tool
Find n-th e Digit is a free online tool that works entirely inside your web browser. Calculate specific digits of Euler's number. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 234 Math utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
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.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
