warning: implicit declaration of function ‘real’; did you mean ‘creal’? #602

Generated code for a form is giving this warning. See eg https://github.com/FEniCS/basix/actions/runs/6094169143/job/16535151559?pr=682

Is this because ufl is asking for the real part or conj of a real number (non complex)? Does it ever ask for imag(x) - I guess that should return zero, in this case...

Yes, I believe that's the issue. It was asking for the real part of one of the coordinates (which is a double)
