Hi @Bensands & welcome to Tulip Community! 🌷

Thanks for the suggestion here. I will raise this with the product team, as this has come up before. You may find some of the discussion on this thread interesting and helpful with a couple workaround options to try and do this with Custom Widgets or using a postgres database connection (though I acknowledge that having this native in expression editor would be easiest!)

> Hello everyone, Does anyone have experience with calculating the arc tangent → arctan(x) for calculating an angle? Because the function doesn’t seem to exist in the expression editor, do you have any good alternatives? Many thanks in advance. Kind regards Paul
