[petsc-dev] should this be moved now?

[Barry Smith]

   With the introduction of PetscPowRealInt() should this be moved to petscmath.h and renamed ?


/* C++ does not promote int64_t to scalar or int32_t for std::pow() */
static PetscScalar Pow(PetscScalar b,PetscInt p)
{
  return PetscPowScalar(b,(int)p);
}
