How to use XNOR Integers
- 1. Paste your integers. Enter two or more integers separated by spaces, such as 12 and 10. Each value is treated as a fixed-width binary number for the bitwise operation.
- 2. Choose the bit width. Set Bit width to 8-bit, 16-bit, 32-bit or 64-bit depending on the register size you are modeling. A narrower width wraps values sooner and changes which bits participate in the result.
- 3. Read the XNOR result. The tool combines all the integers bit by bit using XNOR, which sets a bit to 1 when the corresponding input bits match, so 12 XNOR 10 at 8-bit gives 249.
- 4. Copy the resulting integer. Copy the computed value and use it to verify hardware logic, a digital circuit simulation, or a low-level bit manipulation routine you are debugging.
When to use XNOR Integers
XNOR Integers computes the bitwise XNOR, the equivalence operation, across a list of whole numbers at a chosen bit width. It is for digital logic work where you need to check which bits agree between two or more values rather than which differ.
- Verifying a digital logic circuit. You are simulating an XNOR gate in a circuit design and want to confirm the expected output for specific input values like 12 and 10 at a given bit width.
- Checking a bit-equality mask. A comparator circuit or software routine flags which bits are identical between two registers. Computing XNOR directly shows exactly which bit positions match.
- Studying for a computer architecture exam. You need to practice bitwise operations on fixed-width integers before an exam, and want to confirm your hand-worked XNOR result against the correct 8-bit or 16-bit answer.
- Debugging a low-level firmware routine. Firmware code uses XNOR to detect matching flag bits across two 32-bit status registers, and you want to reproduce the exact result outside the embedded environment.

About the XNOR Integers tool
XNOR Integers does its work locally, right in the browser. Bitwise-XNOR a list of integers within a fixed bit width. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Integer Tools collection on EditSafely, a set of 133 small, focused Integer utilities that share the same instant, private workspace.
You can shape the output with the Bit width setting, and the result refreshes the moment you change it. 2 worked examples further down the page show exactly what the tool produces for real inputs.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Does XNOR Integers cost anything?
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?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
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?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
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.
