`math.sinh()` returns the hyperbolic sine of `x`.

##### Function type signature

```js
(x: float) => float
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### x

(Required) Value to operate on.

## Examples

-   [Return the hyperbolic sine of a value](#return-the-hyperbolic-sine-of-a-value)
-   [Use math.sinh in map](#use-mathsinh-in-map)

### Return the hyperbolic sine of a value

```js
import "math"

math.sinh(x: 1.23)// 1.564468479304407

```

### Use math.sinh in map

```js
import "math"
import "sampledata"

sampledata.float()
    |> map(fn: (r) => ({r with _value: math.sinh(x: r._value)}))
```
