{{alias}}( x )
    Computes the inverse coversed cosine.

    The inverse coversed cosine is defined as `asin(1+x)`.

    If `x < -2`, `x > 0`, or `x` is `NaN`, the function returns `NaN`.

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

    Returns
    -------
    y: number
        Inverse coversed cosine.

    Examples
    --------
    > var y = {{alias}}( -1.5 )
    ~-0.5236
    > y = {{alias}}( -0.0 )
    ~1.5708
