I have a Spark dataframe with decimal column. I want to convert this column to a binary string. Are there any function for this can anybody help?
Thank you!
There is a bin inbuilt function which states
An expression that returns the string representation of the binary value of the given long column. For example, bin("12") returns "1100".
So if you have a dataframe as
+-----+
|Value|
+-----+
|4 |
+-----+
root
|-- Value: decimal(10,0) (nullable = true)
You can use bin
function as
import org.apache.spark.sql.functions._
data.withColumn("Value_Binary", bin(col("Value")))
which should give you
+-----+------------+
|Value|Value_Binary|
+-----+------------+
|4 |100 |
+-----+------------+
root
|-- Value: decimal(10,0) (nullable = true)
|-- Binary_value: string (nullable = true)
