PostgreSQL ASINH() Function

The PostgreSQL ASINH() function returns inverse hyperbolic sine of a value. The inverse hyperbolic sine of x is defined as:

Syntax

ASINH(x)

Parameters

`x`	`Required.` Specify the value.

Return Value

Returns the inverse hyperbolic sine of the value.

Example 1:

The example below shows the usage of ASINH() function.

SELECT ASINH(1);
Result: 0.881373587019543

SELECT ASINH(2);
Result: 1.4436354751788103

SELECT ASINH(3);
Result: 1.8184464592320668

SELECT ASINH(-1);
Result: -0.881373587019543

SELECT ASINH(-2);
Result: -1.4436354751788103

Example 2:

Consider a database table called Sample with the following records:

Data	x
Data 1	1
Data 2	5
Data 3	10
Data 4	-5
Data 5	-10

The statement given below can be used to calculate the inverse hyperbolic sine of records of column x.

SELECT *, ASINH(x) AS ASINH_Value FROM Sample;

This will produce the result as shown below:

Data	x	ASINH_Value
Data 1	1	0.881373587019543
Data 2	5	2.3124383412727525
Data 3	10	2.99822295029797
Data 4	-5	-2.3124383412727525
Data 5	-10	-2.99822295029797
