[LON-CAPA-users] Forcing integer answer

[Lars Jensen]

How do I force the student to enter an integer answer. Say that the
answer is 155 and I want to allow 154, 155, 156 as only possible
answers. Values between these are not allowed. If I set the tolerance to
1 the system allows values in between, and setting the format to "0f"
only affects the display, not the student input. Is there some way I can
force the answer to be an integer?

Lars.
