Corrections

How to report an error

Send the page address, the inputs you used, the result you got and the result you expected, with the source you are relying on, to the contact page. An error in a figure or a formula is treated as the highest priority category of report.

What happens next

1. The formula is re-derived from its cited source.
2. The worked examples are re-run against an independent implementation.
3. If the disagreement is real, the page is corrected and the formula test is added to the page's test set so the same error cannot return unnoticed.
4. The change is recorded below with the date and a description of what was wrong.

What counts as a substantive correction

A change to a formula, to a default input, to a cited external figure, or to a stated interpretation of a result. Typographical fixes and wording improvements are not logged here. Silent substantive edits are not made.

Log

No substantive corrections have been recorded to date. This site is new — publication began in October 2026 — and an empty log at this stage reflects the absence of reported errors so far, not a claim that no error exists.

Entries will list the page, the date, and what was changed. Entries are not deleted when a page is retired.
