> Binary Arithmetic operators should include the evalMode during makeCopy.
> Otherwise, the following query will throw DIVIDE_BY_ZERO error instead of
> returning null
>
> {code:java}
> SELECT try_divide(1, decimal(0)); {code}
> This is caused from the rule DecimalPrecision:
> {code:java}
> case b @ BinaryOperator(left, right) if left.dataType != right.dataType =>
> (left, right) match {
> ...
> case (l: Literal, r) if r.dataType.isInstanceOf[DecimalType] &&
> l.dataType.isInstanceOf[IntegralType] &&
> literalPickMinimumPrecision =>
> b.makeCopy(Array(Cast(l, DataTypeUtils.fromLiteral(l)), r)) {code}
