# pandas.api.typing.Rolling.min

Rolling.min(numeric_only=False, engine=None, engine_kwargs=None)

  Calculate the rolling minimum.

  Parameters:
    numeric_only bool, default False

      Include only float, int, boolean columns.

    engine str, default None

      - `'cython'` : Runs the operation through C-extensions from cython.

      - `'numba'` : Runs the operation through JIT compiled code from numba.

      - `None` : Defaults to `'cython'` or globally setting `compute.use_numba`

    engine_kwargs dict, default None

      - For `'cython'` engine, there are no accepted `engine_kwargs`

      - For `'numba'` engine, the engine can accept `nopython`, `nogil` and `parallel` dictionary keys. The values must either be `True` or `False`.

      The default `engine_kwargs` for the `'numba'` engine is `{'nopython': True, 'nogil': False, 'parallel': False}`.

  Returns:
    Series or DataFrame

      Return type is the same as the original object with `np.float64` dtype.

  Examples

  Performing a rolling minimum with a window size of 3.

      >>> s = pd.Series([4, 3, 5, 2, 6])
      >>> s.rolling(3).min()
      0    NaN
      1    NaN
      2    3.0
      3    2.0
      4    2.0
      dtype: float64
