In case of floating-point and specify the number of decimal places, Serial.print() supports rounding. 0 to 4 then rounddown, 5 to 9 then round up. so the original text Serial.print(1.23456, 4) gives "1.2345" should be: Serial.print(1.23456, 4) gives "1.2346" I checked the result on TINKERCAD and update line is correct.
