Good afternoon,

I am looking to limit the number of decimal
this

Code:

myString.print(falt,DEC);

return 54.000000000
and I would like to have 54.00

Many thank

float f = 54.00000000;
Serial.print(f, 2);

If 54.00000 is a string your print statement wont work, ==> you need to convert the string to a float first ....

You are telling it to print 10 decimal places. Why?

DEC is a #define with a value of 10.

Thank for your help

Code:

myString.print(falt,DEC);

What type of object is 'myString'?

[Reply #5 on:]

Hello

myString is declared like this

PString myString(buffer,sizeof(buffer));

Did I answer to your question?

I solved my probleme like @robtillaart suggeseted

Serial.print(value, 2)

Yes. Your answer tells us that to understand your original problem, it is necessary to look at the interface to the PString class. That's where you should have looked, to understand why the call to print() wasn't doing what you expected. (The online documentation I found at http://arduiniana.org/libraries/PString didn't have any detail about the API, but presumably it's documented somewhere.)

If you download the library, though, you see that PString derives from Print, so the other threads are correct.

The API documentation is the code? Sadly, that's not as unusual as it should be.

It is for me. It's never wrong. It's never three versions behind.
