At this point, it looks like the bug has been fixed. I checked my Access 2016 (32 bit and 64 bit) installations on Win10. I see the full set of values for number datatypes.

Job well done, Access Team.
There is a bug in Access 2016. The MS Access team is aware of it, and is working on a fix for it. No ETA yet on when it will be available.
It involves the Datatype dropdown for Numbers.
Only the default datatype is available.
If you need to change or add number fields, the work around is to go to Options for Object Designers and change the Default Datatype for numbers to the one you need. It then becomes available in the dropdown in place of Long Integer.
There have been some reports that Wizards may also be broken. That, however, hasn't been widely confirmed.
ScottGem, Access MVP and UA VIP, is in contact with the Access development team and will let us know as soon as he gets any update.Update regarding this bug
