# 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

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

      >>> x = np.ma.array([0, 1.], fill_value=-np.inf)
      >>> x.fill_value
      np.float64(-inf)
      >>> x.fill_value = np.pi
      >>> x.fill_value
      np.float64(3.1415926535897931)

  Reset to default:

      >>> x.fill_value = None
      >>> x.fill_value
      np.float64(1e+20)
