Who publishes this site?
Computandum is an independent calculator and reference project. The publisher name is Computandum. We do not claim professional qualifications, third-party endorsement or expert review that has not taken place.
How content is produced
Some drafts and implementation work are AI-assisted. Published methods must be tied to a defined calculation, explicit inputs, supported sources and working examples. Automated checks are useful evidence, but do not replace qualified review for a consequential decision.
What is checked
Checks include executable formulas, independent worked fixtures, invalid inputs, unit compatibility, link integrity, canonical URLs and applicable disclaimers. Financial arithmetic uses decimal calculations; exact integer tools preserve large integers. Scientific and unit calculations state their rounding and assumptions.
What a source date means
A date beside a source records source access or verification scope as stated by the page. It is not a claim that the whole article was professionally reviewed on that date. Official laws, rates, scientific models and product specifications may change; the applicable version and stated exclusions matter.
Limits and regulated topics
Reference results do not establish safety, clinical diagnosis, structural capacity or compliance with an installation code. The publication policy blocks prohibited purposes and requires sources, assumptions and appropriate limitations for permitted regulated tools. A disclaimer cannot make a prohibited purpose publishable.
Corrections and pending review
For a reproducible issue, record the page URL, input values, expected result, actual result and supporting source. Individual editorial review remains pending on parts of the catalogue, including explicitly owner-indexed SI pairs. We do not label automated coverage as completed human review.
Search and performance claims
Search-engine rankings are not guaranteed. Performance reports are measurements of the cited URL, device and time; they are not proof that every page or every real-user visit has the same score. Lab reports and real-user measurements have different scopes.
