binary_float & binary_double do not appear in schema browser

The Schema Browser seems to show attributes of datatype binary_float & binary_double in the Columns tab fine. However, when I go to the Data tab I don’t see the columns at all. In fact, they don’t even show up in the Column Selector pull-down list.

I’m currently using Toad Xpert edition v10.6 w/ Oracle 10gR2. Will this be resolved in v 11.5?

Thanks,
Mitch
