base $10$ otherwise. Note that you may want to specify the base $10$ explicitly
if you are parsing the numbers which may have leading zeroes as otherwise the
string {\tt "09"} may not be parsed correctly: it would be understood as an
octal number because of the leading zero and the parsing would then fail as
{\tt '9'} is not a valid octal digit.
