### ASINH

#### Description
The `ASINH` function is used to calculate the inverse hyperbolic sine of a given numeric expression. The inverse hyperbolic sine function is the inverse of the hyperbolic sine function, and its result will return a hyperbolic sine value related to the input value.

#### Syntax
```
ASINH(expr)
```
#### Parameters
- `expr`: The numerical expression for which the inverse hyperbolic sine value needs to be calculated, of type `DOUBLE`.

#### Return Value
Returns the inverse hyperbolic sine value related to the input expression, of type `DOUBLE`.

#### Example Usage
1. Calculate the inverse hyperbolic sine value of 0:
```sql
SELECT ASINH(0);
-- Result: 0.0
```
In this example, the input value is 0, and its inverse hyperbolic sine value is also 0.

2. Calculate the inverse hyperbolic sine value of -1:
```sql
SELECT ASINH(-1);
-- Result: -0.8813735870195429
```
In this example, the input value is -1, and its inverse hyperbolic sine value is approximately -0.8814.

3. Calculate the inverse hyperbolic sine value of a positive and a negative number:
```sql
SELECT ASINH(2), ASINH(-2);
-- Result: 1.4436354751788103, -1.4436354751788103
```
In this example, we calculate the inverse hyperbolic sine of the positive number 2 and the negative number -2, resulting in 1.4431 and -1.4431, respectively.

4. Calculate the inverse hyperbolic sine of a smaller negative number and a larger positive number:
```sql
SELECT ASINH(-0.1), ASINH(3);
-- Result: -0.09983407889920758, 1.8184464592320668
```
In this example, we calculated the inverse hyperbolic sine values of the smaller negative number -0.1 and the larger positive number 3, resulting in -0.1001 and 1.8831, respectively.

From the above example, you can see that the `ASINH` function can handle inputs of different positive and negative values and return the corresponding inverse hyperbolic sine values. This makes the `ASINH` function very useful in mathematical calculations and data analysis.
