About this page

Use this page to request a calculator we have not built yet, report a formula error, suggest a correction, or ask about the library. Calculator requests and error reports are read by the team that builds the tools.
When we confirm a reported error, we fix the formula and add an automated test that locks in the correct behavior so the same mistake cannot come back. Corrections are treated as a normal part of maintaining a reference.
For advertising and sponsorship, see the advertising page, which covers the audience, placements, and how to start a campaign conversation.
