> according to `TypeCoercion` logic it should automatically hoist both INT-LONG and FLOAT-DOUBLE in Calcite. it is also possible the cast is there for null vs. non-null which also will trigger a type coercion logic. > > I will take a look and see what's the appropriate overwrite for this one. I found that the CAST will happen based on the evaluation of this [function](https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/rel/type/RelDataTypeSystemImpl.java#L62). The `CAST` transformation applies to the data type with lower precision. In the case of INT-LONG, Integer has lower precision(10) vs BigInt(19). However, In the case of FLOAT-DOUBLE, both have the same precision and hence CAST applies to the RHS. I override the method in my latest commit by assigning `DOUBLE` more precision value than `FLOAT`. -- This is an automated message from the Apache Git Service.
