Thanks for the quick reply,

Unfortunately it still doesn't work..

float RTCVar;
float seconds                          =   0;    
int unsigned long   millisVar          =   0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  seconds = floor((millis() - millisVar) / 1000);
  RTCVar = ((1/36)*((-pow(seconds-60,2))))+100;
  Serial.print(seconds);
  Serial.print(" - ");
  Serial.println(RTCVar);
  delay(200);
}
