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.
