Which issue does this PR close?
Closes #1729
Rationale for this change
#1729 was opened due to PR #1728 (comment #1728 (comment))
Later #3675 disabled
ceilandfloorfor decimals.However, the rust test cases added in #1728 are incorrect in my opinion. When spark
ceil/floor, Spark changes precision and scale. And later result precision and scale are set at https://github.com/apache/datafusion-comet/blob/main/native/spark-expr/src/math_funcs/ceil.rs#L51The output of
decimal_ceil_fis intermediate result. Therefore.decimal_ceil_fis correct and the expected values of rust test cases are incorrect.What changes are included in this PR?
Corrected the rust test cases. Enabled
