----------------------------------------------------------------
[~FrankZou] That makes sense.
For overflow, my early attempt looks something like this:
{code:java}
private static boolean isOverflow(BigDecimal b0) {
return b0.compareTo(BigDecimal.valueOf(Long.MIN_VALUE)) < 0 ||
b0.compareTo(BigDecimal.valueOf(Long.MAX_VALUE)) > 0;
}
{code}
This is a helper that could be used in {{SqlFunctions}}. Thoughts?

> Project: Calcite
> Issue Type: New Feature
> Reporter: Dan Zou
> Assignee: Dan Zou
> Priority: Major
>
> Add support for SAFE_ADD, SAFE_SUBTRACT, SAFE_MULTIPLY, SAFE_DIVIDE and
> SAFE_NEGATE in BigQuery.
> Function description:
> * SAFE_ADD: Equivalent to the addition operator '+', but returns NULL if
> overflow occurs.
> * SAFE_SUBTRACT: Returns the result of Y subtracted from X. Equivalent to the
> subtraction operator '-', but returns NULL if overflow occurs.
> * SAFE_MULTIPLY: Equivalent to the multiplication operator '*', but returns
> NULL if overflow occurs.
> * SAFE_DIVIDE: Equivalent to the division operator '/ ', but returns NULL if
> an error occurs, such as a division by zero error.
> * SAFE_NEGATE: Equivalent to the unary minus operator '-', but returns NULL
> if overflow occurs.
> See more details in [BigQuery
