Whenever I create a float variable, it is rounded to 4 digits. Shouldn't floats be able to store more precise decimals than just 4 digits? See below
"myFloat" is a float is declared and then printed to Serial:
But the Serial Monitor shows that the myFloat has been rounded to only 4 digits:
Is there a way to stop this rounding? It is the same when I make it a double instead of a float too.
Yes, all you have to do is read the documentation
https://www.arduino.cc/reference/en/language/functions/communication/serial/print/
Try … Serial.println(myfloat,4);
Remember that an Arduino UNO/Nano/Mega 'float' can only hold about 6.8 significant digits. You can say:
Serial.println(myfloat, 10);
and it will show 10 digits after the decimal point, but after the first 6 or 7 digits (including the two before the decimal point), the digits will be fairly random.
