The “Is a number?” feature that existed in the MIT version (App Intventor) really saved time (and resources) in my project. Miss that alot. ---

Hi Tatian Hmmm is this avilble in DnD? I cant find it - But im probably not llooking enough… The one that existed before was a simple Q “Is a number?” And the response was of course True or False… But appreciate your help here - Could be used untill the other one is coming… And if i find it… 😃 ---

Simply add the data you want to check to a number. If the answer in `NaN` then the data you have in not a number. **[Update]** Check this ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/b/ab85e17be52a067a4c32f15ae25a5bbb00092e5a.png) This is the result ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/a/4a544631f30d4f589e8d1d7936f312685a24004f.png) I changed the variable to 1a1 instead of 121 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/0/6066022a620fbd6d250ae76adfd90f0a5f2d76c7.png) It gives this result ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/0/a0eaf9aac956fc85ff736f45bc870c8b4a4daa9d.png) ---

Yes, in DnD. The “is divisible by” block appears as the “is even” block in the Math drawer. See this: > **[Math](https://docs.thunkable.com/math#analyze-numbers)** ---
