Is it enough *unsigned long* ?

A better fix would probably be to use String::number instead of String::format.

That’s right. In our code we use the name “unsigned long” for this type, not “long unsigned int”, which is equivalent, but not idiomatic. When landing this please use “unsigned long” rather than “long unsigned int”.

As Darin said, please use String::number instead of String::format.

Sorry for my carelessness.
I didn't read the upper part about String::number.

I'll apply those and upload again.
Thanks :)
