[jira] [Created] (SPARK-8822) clean up type checking in math.scala

Reynold Xin created SPARK-8822:
----------------------------------

             Summary: clean up type checking in math.scala
                 Key: SPARK-8822
                 URL: https://issues.apache.org/jira/browse/SPARK-8822
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
            Reporter: Reynold Xin
            Assignee: Reynold Xin


There are various issues w.r.t. type checking in math.scala. Most of the custom implementation of checkInputTypes can be replaced with mixin ExpectsInputTypes.

There are also other minor issues, such as over complicating certain expressions due to the previous lack of implicit type casting among numeric types.
