PetscReal
PETSc type that represents a real number version of PetscScalar
Notes
For MPI calls that require datatypes, use MPIU_REAL as the datatype for PetscScalar and MPIU_SUM, MPIU_MAX, etc. for operations.
They will automatically work correctly regardless of the size of PetscReal.
See PetscScalar for details on how to ./configure the size of PetscReal.
