 ```Hello everyone! (again) ```I got a question. Given a hexadecimal number (ie. 0x13), how can I convert that to the string "13"? I use print() and it gives me a random ASCII character. ``` Is this possible? Thanks in advance. ```

 In reply to this post by Romulo Bahiense ```-- Convert a char to it's ASCII code ("\r" -> 13, "\n" -> 10 ) ```print( string.byte( c ) ) ```Thank you very much; that did the job. ``````> I use print() and it gives me a random ASCII character ```Random? ```Random in the sense of output I did not appreciate.
