Thanks for appreciation @Mohamed_Tamer and @golumaths100 and @JaviR3TicS :grin:

I know there is this function in one of the colin tree extension, but it uses double type, which has a limit.
And mine uses the BigDecimal, so theoretically it can be as much as the memory can handle.

Thanks @The_K_Studio :grinning:

Nice job. Did some tests.

Could you make it so that if the list contains characters like in the example instead of numbers the "do it message displays “expect numbers”. Now it is showing “empty-string” but that isn’t true. It gets a string but not the string it expects.

So you want to add function such that it can compare text too?

If you could add that that would be great. But it would get the same function as the compare text block it think. What i meant was that i would not expect an empty string message. I would like to see a message that would state that i have to use numbers when using the extension.

Because I am using the when error occurred event, it is impossible for me to throw error :sweat_smile:

Maybe I will add a if nothing return, like the tinyDB if not found, but I don’t know how to koders think.

When i do this

And use the error block with a label i get a

For input string: “a”

message.

Btw, i think you need to change your extension’s icon.
See:

And don’t forget to make its size 16×16 :wink:
Also i have some other suggestions:
1- make the extension’s blocks returns an int and not String.So We can use it in another blocks that require its input to be int.
2- Make your try-catch block inside the else condition here.So it doesn’t execute except there isn’t any error:

3- As @Peter said make the extension return something when an error occurred and not an empty string.Its better to return 0 or -1 for example so it can work with my first suggestion ( returning an int ) :slightly_smiling_face:.

I can perfectly load my icon. But it is 48x48

But if the list contain decimal, this won’t work.

Will do, thanks!

Because this extension will return a number, user won’t know if it is the result, or an error.
Maybe I shall return like "null" or "error"
