The mathematical constants finally appear in in C++20, we require only C++17. M_PI is POSIX. It is also in \<QtMath> as well as qDegreesToRadians and qRadiansToDegrees.
I leaning toward your plan "quit thinking about this and move on", this PR is already merged.
The extra digits did change the mantissa by ~2000 on my 64 bit system.
