float hic = dht.computeHeatIndex(t, h, false);                 dtostrf(hic, 6, 2, celsiusTemp);                       float hif = dht.computeHeatIndex(f, h);          dtostrf(hif, 6, 2, fahrenheitTemp);                   dtostrf(h, 6, 2, humidityTemp);
hello, I am having some trouble understanding some lines of my project of DHT11 sensor and I am usig my Arduino IDE.
