{{alias}}( x )
    Computes the hyperbolic arcsine of a number.

    Parameters
    ----------
    x: number
        Input value.

    Returns
    -------
    out: number
        Hyperbolic arcsine (in radians).

    Examples
    --------
    > var v = {{alias}}( 0.0 )
    0.0
    > v = {{alias}}( 2.0 )
    ~1.444
    > v = {{alias}}( -2.0 )
    ~-1.444
    > v = {{alias}}( NaN )
    NaN

    // The function overflows for large `x`:
    > v = {{alias}}( 1.0e200 )
    Infinity

    // The function underflows for small `x`:
    > v = {{alias}}( 1.0e-50 )
    0.0
