Thank you for that suggestion, that seems to be indeed a viable option 
(besides linking with the "amalgamation code" and adding the required 
functions via sqlite3_create_function - and probably a bit more 
reliable, too, with respect to "version matching").

In the future the binary distribution of the upcoming Qt 6.5 will enable 
the "math" (and other) functions as well in the Qt SQlite plugin.

Cheers, Oliver
