I would need to convert a decimal number that is calculated by Arduino (eg 1,1234) on the display ... i only get the number 1 without the values after the dot ...
I tried and tried but I can not do it ...
Kindly can you help me?
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
Thanks a lot for the answer...
So if I understand well I have to do:
number=number*10000 //for 4 decimals
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
You might also use the sprintf() function in C/C++ to convert whatever decimal (or binary or hex) number into a formatted text string with a defined number of decimals and even optional left padding. Then, you might send that text string from your MCU to the Nextion.
