But how can I round a number to 2 decimal and still let it be a float? Converts a valid String to a float. Floats have only 6-7 decimal digits of precision. That means the total number of digits, not the number to the right of the decimal point. Unlike other platforms, where you can get more precision by using a double (e.g. up to 15 digits), on the Arduino, double is the same size as float. String a=1.1234567e-02; float B=a.toFloat(); //now is 0.0123456. float … Ask Question Asked 4 years, 8 months ago.
