> Pmod currently throws a divide by zero exception when the right input is 0. It should - like Divide or Remainder - probably return null.
> Here is a small reproducer:
> {noformat}
> scala> sql("select pmod(id, 0) from range(10)").show
> 17/08/03 22:36:43 ERROR Executor: Exception in task 0.0 in stage 3.0 (TID 3)
> java.lang.ArithmeticException: / by zero
> {noformat}
