#include <petscsys.h> PetscComplex number = 1. + 2.*PETSC_i;
Notes: For MPI calls that require datatypes, use MPIU_COMPLEX as the datatype for PetscComplex and MPIU_SUM etc for operations. They will automatically work correctly regardless of the size of PetscComplex
See PetscScalar for details on how to ./configure the size of PetscReal
Complex numbers are automatically available if PETSc was able to find a working complex implementation
