How to use Round Integers
- 1. Paste your integers. Enter one integer per line or separated by another delimiter, so each is independently rounded to your chosen precision.
- 2. Choose a rounding mode. Select Mode from Ceil (round up), Floor (round down), Round (nearest) or Truncate (toward zero), depending on which direction should win on a tie.
- 3. Set the nearest multiple. Enter Nearest multiple to control the precision, such as 10 to round to the nearest ten instead of the nearest one.
- 4. Copy the rounded integers. Copy the resulting list, where every integer has been adjusted to the nearest multiple according to your chosen mode.
When to use Round Integers
Round Integers adjusts a list of whole numbers to the nearest multiple of a value you choose, using ceil, floor, nearest or truncate rules. Use it whenever raw numbers need to snap to a coarser scale, like the nearest ten or hundred, rather than staying exact.
- Bucketing values for a histogram. You have a list of exact measurement values and want them rounded to the nearest ten to group them into cleaner histogram bins for a chart.
- Rounding prices to a display-friendly increment. A pricing list has precise whole-number amounts and needs rounding up to the nearest five or ten for a simplified customer-facing display.
- Testing a rounding function's edge cases. You wrote code that rounds numbers to a given multiple and want to verify ceil, floor and nearest modes all behave correctly on the same set of test values.
- Simplifying a dataset for a quick estimate. You want a rough, rounded version of a precise dataset for a back-of-envelope estimate, without the exact figures cluttering the summary.

About the Round Integers tool
Round Integers is a free online tool that works entirely inside your web browser. Round integers up or down to the required precision. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 133 Integer 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 2 settings, including Mode and Nearest multiple, and the result refreshes the moment you change one. 2 worked examples further down the page show exactly what the tool produces for real inputs.
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.
Frequently asked questions
Is Round Integers free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
