Will try to actually make them const-evaluable. Will reopen then.

Huh, locally tests were passing. Will check what's wrong tomorrow. Also I should remove the native proc implementations now.

The unit test uses approximate equality because of the fact that .NET's trigonometry functions can and do behave differently on different platforms. See the remark here. There is apparently a 1.1920929E-07 difference between Windows and Linux (or at least between my computer and the github actions server). Maybe at some point we will have to use something else than MathF and Math to avoid this issue.
