> UnsafeRow.getDouble and getFloat() return NaN when called on columns that are null, which is inconsistent with the behavior of other row classes (which is to return 0.0).
> In addition, the generic get(ordinal, dataType) method should always return {{null}} for a null literal, but currently it returns the same thing as the more specific getters.
