Alon Doron 0ec7b99ea2 [SPARK-26021][SQL] replace minus zero with zero in Platform.putDouble/Float ... GROUP BY treats -0.0 and 0.0 as different values which is unlike hive's behavior. In addition current behavior with codegen is unpredictable (see example in JIRA ticket). ## What changes were proposed in this pull request? In Platform.putDouble/Float() checking if the value is -0.0, and if so replacing with 0.0. This is used by UnsafeRow so it won't have -0.0 values. ## How was this patch tested? Added tests Closes #23043 from adoron/adoron-spark-26021-replace-minus-zero-with-zero.
