atan2

Compute the angle in radians between the positive x-axis of a plane and the point given by the coordinates Supports Spark Connect.

For the corresponding Databricks SQL function, see atan2 function.

Syntax

Python

from pyspark.databricks.sql import functions as dbf

dbf.atan2(col1=<col1>, col2=<col2>)

Parameters

Parameter	Type	Description
col1	pyspark.sql.Column, column name or float	coordinate on y-axis
col2	pyspark.sql.Column, column name or float	coordinate on x-axis

Returns

pyspark.sql.Column: the theta component of the point (r, theta) in polar coordinates that corresponds to the point (x, y) in Cartesian coordinates, as if computed by java.lang.Math.atan2()

Examples

Python

from pyspark.databricks.sql import functions as dbf
spark.range(1).select(dbf.atan2(dbf.lit(1), dbf.lit(2))).show()
