### Backend CH (ClickHouse) ### Bug description [Expected behavior] and [actual behavior]: According https://archive.apache.org/dist/spark/docs/3.3.0/sql-ref-datatypes.html ``` NaN Semantics There is special handling for not-a-number (NaN) when dealing with float or double types that do not exactly match standard floating point semantics. Specifically: NaN = NaN returns true. In aggregations, all NaN values are grouped together. NaN is treated as a normal value in join keys. NaN values go last when in ascending order, larger than any other numeric value. ``` For example, `select cast('nan' as float) > 0; ` Gluten returns `false`. But vanila return `true`. ### Spark version None ### Spark configurations _No response_ ### System information _No response_ ### Relevant logs ```bash ``` -- This is an automated message from the Apache Git Service.
