Displaying More Digit of Float on LCD and Serial COM

Projects Programming

Hi,
I'm measuring a reference voltage using one of the analog pins and storing the measure value on a float.
When I display the value of the float on the LCD or check in the serial display it only show two decimal places. Can I display more decimal place?

float dRes;
    test=analogRead(A0);
    dRes=map(test,0 ,1023, 0, 6000);//Map A/D digital data. 6V max
    dRes=(dRes/1000);//This is my work around display decimal digit 
    lcd.print(dRes);
    Serial.println(dRes);

My Ref Voltage is 3.3V so I'm using a voltage divider circuit with 9k/11k ratio, the measurement so far is accurate I just want to see more digits if possible.

Thanks

You can specify how many decimal digits to display. The default is 2.

 Serial.println(dRes, 6);   //  Display with 6 fractional digits

Thanks!
It also worked on the LCD display.

lcd.print(dRes, 6);   //  Display with 6 fractional digits
