class_docstr: A column composed of numerical data.
  
  This class encodes a standard interface for different types of columns
  containing numerical types of data. In particular, mathematical operations
  that make sense whether a column is integral or real, fixed or floating
  point, should be encoded here.
code: def _scan(self, op: str) -> ColumnBase:
      return libcudf.reduce.scan(
          op.replace("cum", ""), self, True
      )._with_type_metadata(self.dtype)
