How to print a float using streaming.

Projects Programming
1

I would like to print more numbers after the decimal point.
I know how to do that using the normal print command (Serial.print(azFloat, 4);
But if i use something like this it prints a 4.

  Serial << "azFloat " << (azFloat,4) << " elFloat " << (elFloat,4) << endl;

Anny suggestions?

Provide a link to the library you are using. There is probably a way...

These are the libs i am using:

#include <Wire.h> 
#include <LiquidCrystal_I2C.h>
#include <Streaming.h>

The Streaming.h file contains a comment:

//   Serial << _FLOAT(gps_latitude, 6); // 6 digits of precision

Have you tried this?

It Works

I use this function :
dtostrf(floating point number, total length, No of decimals, resultstring);
