# ASINH

Elemental Intrinsic Function (Generic): Produces the hyperbolic arcsine of x.

result = ASINH (x)

x | (Input) Must be of type real or complex.

## Results

The result type and kind are the same as x.

If the result is complex, the imaginary part is expressed in radians and lies in the range - pi/ 2 <= AIMAG (ASINH (x)) <= pi / 2.

Specific Name | Argument Type | Result Type
--- | --- | ---
ASINH | REAL(4) | REAL(4)
DASINH | REAL(8) | REAL(8)
QASINH | REAL(16) | REAL(16)

## Example

ASINH (1.0) has the value -0.88137.

ASINH (180.0) has the value 5.88611.
