For the record, does anyone know the maximum number of decimal places to which Serial.print has been designed?
To my reckoning it appears to be 15d.p. Can anyone confirm this?
PS: as an adjunct to this, how do you print a long double?

In order to print a long double you will need to do something like this:
long double x;
x = 1.123456789123456;
sprintf(myString, "%.15lf", x);
Using this method, you are not limited to the 15 decimal point limit of Serial.print, however, the long double is only accurate up to 15 decimal places. Hope this helps.
