Which functions are used in the formula in the calculation column of the Sharepoint list?

Today, a user wrote an email to me about the formula in the list calculation column when reading the SharePoint Portal Server 2003 deep guide, the book only states that "the calculated value formula also supports many functions. Readers can refer to the SharePoint help documentation for a deeper understanding." So the netizen asked me which functions can be used in the formula in the calculation column of the Sharepoint list.

To be honest, I have never really understood which functions can be used, so I found some help files in the SharePoint guide and finally confirmed the answer to this question.

I put the list of all available functions on this page (accessible). To learn the exact usage of each function, you can use the search function of the SharePoint help document, you can directly search for the function name.
