    Description

      Describe the handling of the ambigous min/max statistics for FLOAT/DOUBLE types in case of TypeDefinedOrder. (See PARQUET-1222 for details.)

      • When looking for NaN values, min and max should be ignored.
      • If the min is a NaN, it should be ignored.
      • If the max is a NaN, it should be ignored.
      • If the min is +0, the row group may contain -0 values as well.
      • If the max is -0, the row group may contain +0 values as well.
