Use the Flow Launcher Calculator and Copy Results

Daily use · Published October 30, 2026 · Publisher: flowlauncher.app

At a glance

Flow Launcher includes a Calculator plugin for evaluating expressions from the search bar. Begin with a simple expression, check the displayed result, and copy it when needed. Decimal separators and output formatting should match the settings and locale you use.

Steps to follow

  1. Ensure Calculator is enabled and inspect whether it uses a dedicated action keyword.
  2. Enter a simple expression such as 2+2 and confirm the expected result before testing more complex syntax.
  3. Inspect the result action or context menu to copy the value, then paste it into a plain-text editor.
  4. Test a decimal expression and review the plugin’s formatting settings, including thousands-separator behavior where available.
2+2
(12+8)/4
Check copied formatting in a text editor.

Check the result

The numeric value is correct for the test expression and the pasted text has the expected decimal and grouping characters.

Limits and common pitfalls

Do not assume the expression grammar matches every programming language or spreadsheet. Validate specialized functions before relying on them for important calculations.

Make the check repeatable

Keep calculator testing separate from web search: a mathematical expression should produce a calculator result, not merely open a search engine. If another plugin captures the expression, inspect action keywords and priorities before changing your Windows regional settings.

Questions and answers

Why does the pasted number contain a different separator?

Number formatting can depend on locale and plugin settings. Compare the displayed value, copied text, and the receiving app’s expectations.
