Frequently asked questions
How precise are the results?
We use double precision floating point math and round to 12 decimal places by default. You can adjust rounding in the settings menu.
Does the tape persist after closing the tab?
Yes. Recent calculations are saved in local storage on your device, so you can return later and continue where you left off.
Can I export results to a spreadsheet?
Click the export button beneath the tape. You can copy the list to the clipboard or download a CSV file.
