pyspark.sql.functions.sinh

pyspark.sql.functions.sinh(col)

Computes hyperbolic sine of the input column.

New in version 1.4.0.

Changed in version 3.4.0: Supports Spark Connect.

Parameters

colColumn or column name

hyperbolic angle.

Returns

Column

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

Examples

Example 1: Compute the hyperbolic sine

>>> from pyspark.sql import functions as sf
>>> df = spark.createDataFrame([(-1,), (0,), (1,)], ["value"])
>>> df.select("*", sf.sinh(df.value)).show()
+-----+-------------------+
|value|        SINH(value)|
+-----+-------------------+
|   -1|-1.1752011936438...|
|    0|                0.0|
|    1| 1.1752011936438...|
+-----+-------------------+

Example 2: Compute the hyperbolic sine of invalid values

>>> from pyspark.sql import functions as sf
>>> spark.sql(
...     "SELECT * FROM VALUES (FLOAT('NAN')), (NULL) AS TAB(value)"
... ).select("*", sf.sinh("value")).show()
+-----+-----------+
|value|SINH(value)|
+-----+-----------+
|  NaN|        NaN|
| NULL|       NULL|
+-----+-----------+
