<A NAME="PetscScalar"><H1>PetscScalar</H1></A>
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
<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
For MPI calls that require datatypes, use <A HREF="../Sys/MPIU_SCALAR.html#MPIU_SCALAR">MPIU_SCALAR</A> as the datatype for <A HREF="../Sys/PetscScalar.html#PetscScalar">PetscScalar</A> and MPIU_SUM, MPIU_MAX etc for operations. They will automatically work correctly regardless of the size of <A HREF="../Sys/PetscScalar.html#PetscScalar">PetscScalar</A>.
