Need atan2 function

I have seen a couple of postings here on the community of people using the atan2() function but I do not see it in the latest firmware. How would I get my hands on a library with this function?

It’s part of the C++ standard - add #include <cmath> to your source code, then it’s ready for use. :smile:
