Read about parseInt.

Thanks a lot!
It was very helpful :slight_smile:

I was wondering the same thing. I really didn’t know how to do this, but fortunately I have found this thread, and now I know about parseInt() function. Thank you so much for your answer, it was very useful. Now I know how to convert binary to a number. By the way, after converting I got the number 511. I have read on that it’s more than just a simple number, it has something special, a hidden meaning, and it’s a sign. Maybe it’s just a coincidence, but I believe that it’s not. However, thank you for your answer, it was very useful.
