+    Notes
+    -------
+    Using include_lowest shifts the lower bound of x by -0.001, 
+    due to the .1% extension on the range x, which makes the 
+    dtype of bin intervals to change from int64 to float64
+
+    Examples
+    --------
+    In:
+    >>> pd.cut(np.array([0, 1, 7]), bins=[0, 3, 6, 8], include_lowest=True)
+    ... # doctest: +ELLIPSIS
+    Out: 
+    [(-0.001, 3.0], (-0.001, 3.0], (6.0, 8.0]]
+    Categories (3, interval[float64]): [(-0.001, 3.0] < (3.0, 6.0] < (6.0, 8.0]]
+
+    The lowermost interval changes from 0 to -0.001 after .1% adjustment
+    which results in change of dtype from int64 to float64
