What to include

Tell us which calculator, the exact inputs you used, the result you got, and what you expected with the reference (standard clause or handbook page) you compared against. Reports that include a verifiable reference are usually fixed within a few days.

Feature requests are welcome too, especially for calculations that are missing from the catalog.
