> We must implement the missing:

> That is:
>          <signed numeric literal> ::= [ <sign> ] <unsigned numeric literal>
>          <unsigned numeric literal> ::= <exact numeric literal> | <approximate numeric literal>
>          <exact numeric literal> ::= <unsigned integer> [ <period> [ <unsigned integer> ] ] | <period> <unsigned integer>
>          <sign> ::= <plus sign> | <minus sign>
>          <approximate numeric literal> ::= <mantissa> E <exponent>
>          <mantissa> ::= <exact numeric literal>
>          <exponent> ::= <signed integer>
>          <signed integer> ::= [ <sign> ] <unsigned integer>
>          <unsigned integer> ::= <digit>...
