I am trying to display a float from an API, however, the default display is 2 decimal points i.e 0.00. I am trying to display a precise number of 4 decimal points (0.0000). For example, my code is listed below.
float duco_price = doc["Duco price"]; String DUCO_PRICE = "Price: " + (String)duco_price; Heltec.display->drawString(40, 30, DUCO_PRICE);
I know the float displays a value up to 6 decimal points as I can view it on the Serial Monitor.
