[jira] [Commented] (SPARK-30762) Add dtype="float32" support to vector_to_array UDF

Currently, all the floating > numbers in a vector is converted to Double in scala. In this issue, we will > add a parameter in the python function {{vector_to_array(col)}} that allows > converting to Float (32bits) in scala, which would be mapped to a numpy array > of dtype=float32. > -- This message was sent by Atlassian Jira (v8.3.4#803005) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
