What have you tried ?

You are in the right place, keep looking…

Or do you want to know what the largest and smallest numbers AI2 can handle. We have covered this before somewhere @ewpatton might be able to remind me…

Strings, numbers, what size can they have?

I’ll address the question in three parts as the actual answer is somewhat complicated. In particular, it’s important to know that at the core of App Inventor is an implementation of the Scheme language called Kawa. Theoretical String Length There are two different internal string types in App Inventor. Kawa provides a mutable string type called FString and then there’s Java’s standard String type. Conversions are done from FString to String on an as needed basis to interact with the parts of th…
