PETSC_STATIC_INLINE PetscInt PetscIntSumTruncate(PetscInt a,PetscInt b)Not Collective
|a||- the PetscInt value|
|b||- the second value|
Use PetscInt64Mult() to compute the product of two PetscInt as a PetscInt64 Use PetscRealIntMultTruncate() to compute the product of a PetscReal and a PetscInt and truncate to fit a PetscInt Use PetscIntMultError() to compute the product of two PetscInt if you wish to generate an error if the result will not fit in a PetscInt
This is used where we compute approximate sizes for workspace and need to insure the workspace is index-able.
