example doesn't compile on Arduino Nano

Arduino Nano compile does not have Serial.printf and even sprintf() does not have %f

FilteredADC:29:12: error: 'class HardwareSerial' has no member named 'printf'; did you mean 'print'?
     Serial.printf("Raw=%d, Filter1=%.3f, Filter2=%.3f", raw, filtered1, filtered2);
            ^~~~~~
            print
