# numpy.ma.masked_array.fill_value

property

property ma.masked_array.fill_value

  The filling value of the masked array is a scalar. When setting, None will set to a default based on the data type.

  Examples

      >>> for dt in [np.int32, np.int64, np.float64, np.complex128]:
      ...     np.ma.array([0, 1], dtype=dt).get_fill_value()
      ...
      999999
      999999
      1e+20
      (1e+20+0j)

      >>> x = np.ma.array([0, 1.], fill_value=-np.inf)
      >>> x.fill_value
      -inf
      >>> x.fill_value = np.pi
      >>> x.fill_value
      3.1415926535897931 # may vary

  Reset to default:

      >>> x.fill_value = None
      >>> x.fill_value
      1e+20
