> > Will this cause the bug to be covered up? The decimal type doesn't seem to have precision errors > > Maybe we should change this back after the decimal v3 is completed. Because currently, the decimal type doesn't return real precision. This fix was introduced for two reasons: 1. The previous fix judges whether two numbers(float & double) are equal by the threshold of relative change. However, this is a fixed value, which may not solve the accuracy problem with larger error, so the rounding method may be better. 2. Other correctness regression tests(tpch 100/1000) are prepared to be added, but the correct result sets come from other frameworks(Trino/Spark). Different frameworks cannot guarantee consistent behavior of decimal. -- This is an automated message from the Apache Git Service.
