Float number output

in c syntax formating float number print 3 digits after decimal

code: [select]

printf("%.3f", variable);

the arduino doesn't seem understand syntax.  

please help

the arduino prints through serial object, uses serial/uart of microchip.

you can see output in serial monitor.

code: [select]


void setup(){
 serial.begin(9600);
 float x = 3.1415;
 serial.println(x);
}

void loop(){/*no loop*/}
