Xiangrui Meng created SPARK-11408:
-------------------------------------

             Summary: Display scientific notation correctly in DataFrame.show()
                 Key: SPARK-11408
                 URL: https://issues.apache.org/jira/browse/SPARK-11408
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.5.1, 1.6.0
            Reporter: Xiangrui Meng


{code}
scala> sqlContext.range(2).select(col("id") / 3e5).show()
+--------------------+
|     (id / 300000.0)|
+--------------------+
|                 0.0|
|3.333333333333333...|
+--------------------+
{code}

The exponential term is omitted, which is error-prone. We should format the numbers properly based on column width.
