They may have said "closed" but the mathematical expression (0,1) designates an "open" interval. Looks like the endpoints 0 and 1 are not
allowed insofar as the "fraction_description" syntax goes. Note that .0 gives you an error and 1.0 is interpreted as a "count_description" (as the
original poster pointed out).
