Hi guys,
For cycling digits, I use

int number[10] = {0,1,2,3,4,5,6,7,8,9};

But in order to have . (decimal) in the input, I need to define it as

int number[11] = {0,1,2,3,4,5,6,7,8,9,.};

But this is an error. If I define as

int number[11] = {0,1,2,3,4,5,6,7,8,9,'.'};

I see 46 on my OLED.

How can I define . (decimal, not float) properly in an array?

Thanks
