Got your idea.

It's not my idea. It's a standard notation.

I'll try use '|' exclusively. Thanks for the suggestions:

   <fixed_point_number>::= [-] <wnum> [ . <frac> ] // excluding "-0" case
   <wnum>::= 0
   <wnum>::= <nzd> { 0 | <nzd> }
   <frac>::= { 0 | <nzd> } <nzd>
   <nzd> ::= 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 // 'digit' varys depending on n-ary

Ex: 78, -12.345, 3.1414159

So what's the point of defining these strings that represent a subset of
the rationals?
