This is about how to ask for integer numbers by STACK design with minimum mouseclics/typing from default input settings.
If I want the students to input an integer number, then I use "Numerical" input with the option
- Forbid floats: yes (in order to restrict to integers) and
- extra option "floatnum" (in order to refuse expressions like 3^2).
It looks very odd and certainly can be done in a better way. Any ideas?
