neoGPS and using (fix.altitude(), 6) as a variable

[mcr5600]

DEBUG_PORT.print( fix.latitude(), 6 ); prints 36.787551 on the serial monitor

if I assign a float variable to it:
lat = (fix.latitude(), 6 );
and send it to the serial port:
DEBUG_PORT.println(lat); it prints 6

if I assign a float variable to this:
lat = fix.latitude(); it prints 36.79

How do I get a variable to yield results like 36.787551 and not 6 or 36.79 ?
Any help would really be appreciated.

@mcr5600

lat = (fix.latitude(), 6 );

Drop the ",6" and look up the comma operator.

The number of decimal places is not defined in a float, but you can specific how many (n) to print with Serial.print(x, n).

@mcr5600

lat = (fix.latitude(), 6 );

You've used the comma operator inadvertently.

  lat = fix.latitude();

is what you want.

Then

  Serial.print(lat, 6);

to print more digits.

Thank you much, that solved my issue and it worked perfectly .
I didn't understand how Serial.Print works.
Thanks again !!!
