Description

We must implement the missing:
<signed numeric literal> ::= !! As defined by SQL-92 grammar.
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>...
