<A NAME="PetscReal"><H1>PetscReal</H1></A>
PETSc type that represents a real number version of <A HREF="../Sys/PetscScalar.html#PetscScalar">PetscScalar</A>
<P>
<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
For MPI calls that require datatypes, use <A HREF="../Sys/MPIU_REAL.html#MPIU_REAL">MPIU_REAL</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/PetscReal.html#PetscReal">PetscReal</A>.
<P>
See <A HREF="../Sys/PetscScalar.html#PetscScalar">PetscScalar</A> for details on how to ./configure the size of <A HREF="../Sys/PetscReal.html#PetscReal">PetscReal</A>.
