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...

plus-sign ::= +

minus-sign ::= -
