Follow-up Comment #22, bug #61300 (project octave): IIUC, an array can't have more elements than the maximum of `octave_idx_type`. `octave_idx_type` is either `int64_t` or `int32_t` depending on the platform. The same should probably be valid for ranges. So, the assignment in comment #20 should be save. IIUC, in your examples in comment #21, the sum `m_limit.value () - m_base.value () + m_increment.value ()` overflows. Would that be different if the result would be cast to `int64_t`? We might want to detect or avoid that overflow. But that is a different issue imho. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?61300> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
