PETSc type that represents a complex number with precision matching that of PetscReal.
PetscComplex number = 1. + 2.*PETSC_i;
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
PetscReal, PetscScalar, PetscComplex, PetscInt, MPIU_REAL, MPIU_SCALAR, MPIU_COMPLEX, MPIU_INT, PETSC_i
