If you are doing further calculations with that data the extra digits will not hurt. Or are you then just displaying that data form the database? Then the best way would be to round in that displaying program. Or you could send the data to firebase as a string. Then you can do the same rounding as with Serial.print() while constructing the string. Though I don't see the use in that. | |
