{{alias}}( z, y )
    Returns a double-precision complex floating-point number with the same
    magnitude as `z` and the sign of `y*z`.

    Parameters
    ----------
    z: Complex128
        Complex number.

    y: number
        Number from which to derive the sign.

    Returns
    -------
    out: Complex128
        Result.

    Examples
    --------
    > var v = {{alias}}( new {{alias:@stdlib/complex/float64}}( -4.2, 5.5 ), -9.0 )
    <Complex128>
    > var re = {{alias:@stdlib/complex/real}}( v )
    4.2
    > var im = {{alias:@stdlib/complex/imag}}( v )
    -5.5
