PetscScalar#
PETSc type that represents either a double precision real number, a double precision complex number, a single precision real number, a __float128 real or complex or a __fp16 real - if the code is configured with –with-scalar-type=real,complex –with-precision=single,double,__float128,__fp16
Notes#
For MPI calls that require datatypes, use MPIU_SCALAR
as the datatype for PetscScalar
and MPIU_SUM
, etc for operations. They will automatically work correctly regardless of the size of PetscScalar
.
