         An ndarray containing the non- ``fill_value`` values.
 
+        This property returns the actual data values stored in the sparse
+        representation, excluding the values that are equal to the ``fill_value``.
+        The result is an ndarray of the underlying values, preserving the sparse
+        structure by omitting the default ``fill_value`` entries.
