Summary

The description for nexttoward() in Annex F should be changed to reference nextafter to be consistent with 7.12.11.4. and F.9.8.3.

Details

Currently, F.9.8.4 has: No additional requirements. From that, one could conclude that there is no required underflow or overflow for nexttoward by annex F. But, F.9.8.3 has two explicit error conditions on nextafter and 7.12.11.4 says nexttoward is similar to nextafter. We need to make it clear that nextafter and nexttoward have the same requirements with respect to range errors in annex F.

Suggested Technical Corrigendum

In F.9.8.4 nexttoward change:

No additional requirements.

to

No additional requirements beyond nextafter.
