public boolean shouldConvertDecimal64ToDecimal()

Description copied from class: VectorExpression

By default vector expressions do not handle decimal64 types and should be converted into Decimal types if its output cannot handle Decimal64. Decimal64 that only deal with Decimal64 types cannot handle conversions so they should override this method and return false.
