The `sinh()` function returns the hyperbolic sine of a specified numeric argument.

## [](#syntax)Syntax

```sql
SINH(x)
```

## [](#arguments)Arguments

-   `x`: A positive or negative number of type `real` or `double precision`.


## [](#return-type)Return type

Same as the input type (`real` or `double precision`).

## [](#examples)Examples

### [](#positive-value)Positive value

```sql
SELECT SINH(1);
```

```sql
       sinh
--------------------
 1.1752011936438014
(1 row)
```

### [](#negative-value)Negative value

```sql
SELECT SINH(-1);
```

```sql
        sinh
---------------------
 -1.1752011936438014
(1 row)
```

### [](#zero)Zero

```sql
SELECT SINH(0);
```

```sql
 sinh
------
    0
(1 row)
```

### [](#expression-argument)Expression argument

```sql
SELECT SINH(2.5 * 0.4);
```

```sql
       sinh
--------------------
