PETSC_STATIC_INLINE PetscErrorCode PetscIntMultError(PetscInt a,PetscInt b,PetscInt *result)Not Collective
a | - the PetscInt value | |
b | - the second value |
Output Parameter:ma
Use PetscIntMult64bit() to compute the product of two 32 bit PetscInt and store in a Petsc64bitInt Use PetscIntMultTruncate() to compute the product of two PetscInt and truncate it to fit in a PetscInt
Developers Note: We currently assume that PetscInt addition can never overflow, this is obviously wrong but requires many more checks.
