In any case, a failed casting operation always +returned undefined, partial results. Those may now be even more +undefined and partial. +For users of the ``NpyIter`` C-API such cast errors will now +cause the `iternext()` function to return 0 and thus abort +iteration. +Currently, there is no API to detect such an error directly. +It is necessary to check ``PyErr_Occurred()``, which +may be problematic in combination with ``NpyIter_Reset``. +These issues always existed, but new API could be added +if required by users. |
