sinh

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

For the corresponding Databricks SQL function, see sinh function.

Syntax

from pyspark.sql import functions as dbf

dbf.sinh(col=<col>)

Parameters

Parameter	Type	Description
col	pyspark.sql.Column or column name	hyperbolic angle.

Returns

pyspark.sql.Column: hyperbolic sine of the given value, as if computed by java.lang.Math.sinh()

Examples

from pyspark.sql import functions as dbf
df = spark.createDataFrame([(-1,), (0,), (1,)], ["value"])
df.select("*", dbf.sinh(df.value)).show()

from pyspark.sql import functions as dbf
spark.sql(
    "SELECT * FROM VALUES (FLOAT('NAN')), (NULL) AS TAB(value)"
).select("*", dbf.sinh("value")).show()
