### Search before asking - [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar. ### Version version 1.3.3 (Build: ad95a7e) ### Describe the bug and provide the minimal reproduce step ``` DROP DATABASE root.db0 CREATE DATABASE root.db0 CREATE TIMESERIES root.db0.t1 WITH datatype=INT32; INSERT INTO root.db0(timestamp, t1) VALUES (1641024000000, 0); # query 1 SELECT t1 FROM root.db0 WHERE (-1) * t1 == 0; # query 2 SELECT t1 FROM root.db0 WHERE (-1) * t1 == -0.0; ``` ### What did you expect to see? Query 1 returned result set: **0** Query 2 returned result set: **0** ### What did you see instead? Query 1 returned result set: **empty set** Query 2 returned result set: **0** ### Anything else? Dear IoTDB team, In the query above, the result of the expression `(-1) * t1` is `-0.0`. In principle, this value should be equivalent to `0`. However, a comparison of the results from Query 1 and Query 2 indicates that the two are not equal. ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
