Exemples

Python

from pyspark.sql import functions as dbf
spark.sql(
    "SELECT * FROM VALUES (0.0), (PI() / 2), (PI() / 4) AS TAB(value)"
).select("*", dbf.sin("value")).show()

Output

+------------------+------------------+
|             value|        SIN(value)|
+------------------+------------------+
|               0.0|               0.0|
