static inline PetscErrorCode PetscIntSumError(PetscInt a,PetscInt b,PetscInt *result)Not Collective
| a | - the PetscInt value | |
| b | - the second value |
| c | - the result as a PetscInt value, or NULL if you do not want the result, you just want to check if it overflows |
Use PetscInt64Mult() to compute the product of two 32 bit PetscInt and store in a PetscInt64 Use PetscIntMultTruncate() to compute the product of two PetscInt and truncate it to fit in a PetscInt
