asin

Computes inverse sine of the input column. Supports Spark Connect.

For the corresponding Databricks SQL function, see asin function.

Syntax

Python

from pyspark.databricks.sql import functions as dbf

dbf.asin(col=<col>)

Parameters

Parameter	Type	Description
col	pyspark.sql.Column or column name	target column to compute on.

Returns

pyspark.sql.Column: inverse sine of col, as if computed by java.lang.Math.asin()

Examples

Python

from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([(-0.5,), (0.0,), (0.5,)], ["value"])
df.select("*", dbf.asin(df.value)).show()

Output

+-----+-------------------+
|value|        ASIN(value)|
+-----+-------------------+
| -0.5|-0.5235987755982...|
|  0.0|                0.0|
|  0.5| 0.5235987755982...|
+-----+-------------------+

Python

from pyspark.databricks.sql import functions as dbf
spark.sql("SELECT * FROM VALUES (-2), (2), (NULL) AS TAB(value)").select("*", dbf.asin("value")).show()

Output

+-----+-----------+
|value|ASIN(value)|
+-----+-----------+
|   -2|        NaN|
|    2|        NaN|
| NULL|       NULL|
