MIT App Inventor whole number division

[Ben_Fenton]

I am creating a multiplication app with adding, subtracting, division and multiplication but I am having trouble with the division question as both numbers need to be between 1 and 12 and the answer has to be a whole number.
any help would be appreciated

Check if number is an integer

This is my first post here; correct me if I am doing anything wrong. My question is: how can I check if number is an integer? Do I have to create a custom function or is there a built - in function for that? If there is no built - in function, that's what I've made so far (edit: just realised I can't use floor like that): [blocks] (I am new with functions in MIT App Inventor, so didn't know how to set 'boolean' to a value. Correct me if I am doing anything wrong.)
