## Arguments

`x`

- The type shall be `real`

or `complex`

.

## Return value

The return value is of the same type and kind as `x`

. If `x`

is complex, the imaginary part of the result is in radians and lies between $-\pi/2 \leq \mathop{Im}{\asinh(x)} \leq \pi/2$.

## Example

```
program test_asinh
real(8), dimension(3) :: x = (/ -1.0, 0.0, 1.0 /)
write (*,*) asinh(x)
end program
