Keysheet is an independent project. Feedback — a wrong answer, a keystroke sequence that does not match your BA II Plus, a translation issue, or a suggestion for another worksheet — is very welcome.

Reporting calculation bugs

Please include the worksheet, every input value, P/Y and C/Y, BGN/END, the answer Keysheet shows, and the answer your physical calculator shows. The computation core is unit-tested against verified reference values, so a mismatch is treated as a bug.
