Code completion does not cover documented Javascript functions

There is a list of supported Javascript functions in Qt documentation here:
https://doc.qt.io/qt-5/qtqml-javascript-functionlist.html

When I type "Math." in Qt Creator in a QML file, many of the functions listed in the documentation for the Math module are listed. However, some are missing, e.g. "Math.trunc", "Math.log10".

I would suggest to make sure that at least everything that is documented on Qt's documentation page above should be added to code completion.
