Looks like an error in the description of canonical represention. The canonicl represention is defined by prohibiting certain lexical representation, but "-0.0" is not prohibited, as you've observed. However, there is no negative zero in the value space of decimal, so "-0.0" presumably represents the same value as "0.0" (but, by definition, only one of them can be the canonical representation). Or perhaps it is an error that "-0.0" is a valid lexical representation at all. xan
