JiJun Tang commented on FLINK-4621:
-----------------------------------

I think simple numbers can be coverted to Java primitives.For exmaple : -0.5 -> longval=-5,precision=1

> Currently, all SQL {{DECIMAL}} types are converted to BigDecimals internally. By default, the SQL parsers creates {{DECIMAL}} literals of any number e.g. {{SELECT 1.0, 12, -0.5 FROM x}}. I think it would be better if these simple numbers would be represented as Java primitives instead of objects.
