Integer input in STACK

by Martin Kraska - Wednesday, June 17, 2020, 1:12 AM

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?

The above procedure was not correct, can't reproduce how this could have worked

So for now I settle for these non-standard settings when I want integer input:

Input type: numerical
forbid floats: no (as otherwise typing floats leads to a validation message recommending fractions)
extra options: maxdp:0 (this silently converts any float into an integer at validation)

However, this does not reject expressions like 3*5. Do I really need to forbid math operations explicitly?

Chris,

If I understand your commit correctly, than it will be sufficient to select "numerical" input and provide the extra option "intnum". That seems to be straightforward. Thank you for implementing this.
