How to use Binary / Hex Math

What it does

Perform arithmetic on binary or hexadecimal operands and view results across bases. It runs entirely in your browser — your input never leaves your device.

Options

Every setting this tool exposes, straight from the code that validates it.

Example

Try it with these settings on the tool page:

• left: line one
• right: line two
• base: 2
• operation: add

Getting the result you want

Most of the control here is in the options above. If the output is not what you expected, the setting to check first is base and operation — those change the shape of the output rather than the input it accepts.

Troubleshooting

• Nothing happens / the output stays empty. left, right are required — the tool waits until you provide them.
• It is slow on very large input. Everything runs in your browser, so speed depends on your device. Very large inputs are best split up, or run through the API where the work happens on our servers.

Automating it

The same logic is available as a REST endpoint, so you can run it from a script, a CI job or your own app.

Bash
curl "https://api.toolsxpo.com/v1/binary-math" \
  -H "Authorization: Bearer $TOOLSXPO_KEY"

It costs 1 credit per successful call. See the full endpoint reference, or try it in the playground.
