Well, I *can* understand that printf () isn't prepared to handle numbers
with 190 digits :)

Well, I doubt that
2286484951194899000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
is more human-readable than
2.2864849511949E+190
Perhaps you want to change it to
2.2864849511949 * 10^190
But I'd say adding a note explaining the "E" notation is simpler...
PS: The long number is, scientifically seen, also *less* correct than the
'E' form - the 'E' form states that it is a number with a precision of 16
digits, while the long one implies that it has a precision of 190 digits
(which is definitely wrong).
