Hello,

Thank you all for the help ...

The solution to the "problem":

myNextion.setComponentText ("MainPage.t1", String (number,
3));

Where ,3 indicates the digits after zero

just multiply with

- 10 for one decimal

- 100 for two decimals

- 1000 for three decimals

- 10000 for four decimals

Hi Gerry,

Thanks a lot for the answer...

So if I understand well I have to do:

........

number=number*10000 //for 4 decimals

myNextion.setComponentValue("MainPage.n1",(number));

1.12345 * 10000 =11234.5 as float and 11234 as integer

and we know, from 11234 the most right 4 numbers are always the decimal part ...

Okay, tonight I try and let you know ...

thank you so much
