-----------------------------------

             Summary: The sqrt/power function not accept the real data types.
                 Key: FLINK-4743
                 URL: https://issues.apache.org/jira/browse/FLINK-4743
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
    Affects Versions: 1.1.1
            Reporter: Anton Mushin


At time calculate the sequences sql aggregate functions for real type column, got exception:
No applicable constructor/method found for actual parameters "float, java.math.BigDecimal"
And for column of integer type the problem does not occur.

Code reproduce:
{code}
@Test
  def test():Unit={
    val env = ExecutionEnvironment.getExecutionEnvironment
    val tEnv = TableEnvironment.getTableEnvironment(env, config)
    val ds = env.fromElements(
      (1.0f, 1),
      (2.0f, 2)).toTable(tEnv)
    tEnv.registerTable("MyTable", ds)
    val sqlQuery = "SELECT " +
      "SQRT((SUM(a*a) - SUM(a)*SUM(a)/COUNT(a))/COUNT(a)) "+
      "from (select _1 as a from MyTable)"
    tEnv.sql(sqlQuery).toDataSet[Row].collect().foreach(x=>print(s"$x "))
  }
{code}
got exception:
