it works like a charm! tested with
```
disp.set("HH");
disp.set("H------H");
disp.set(3);
disp.set(3.1);
disp.set(3.14);
disp.set(3.14159);
disp.set(3.14159+"H");
disp.set("3.14159H");
```
Everything is working as expected. Thank you very much @Gordon !!

Regarding the above testing, I think the module can be upgraded :)
