{{alias}}( α, s, m )
    Returns the standard deviation of a Fréchet distribution with shape
    parameter `α`, scale parameter `s`, and location `m`.

    If provided `0 < α <= 2` and `s > 0`, the function returns positive
    infinity.

    If provided `NaN` as any argument, the function returns `NaN`.

    If provided `α <= 0` or `s <= 0`, the function returns `NaN`.

    Parameters
    ----------
    α: number
        Shape parameter.

    s: number
        Scale parameter.

    m: number
        Location parameter.

    Returns
    -------
    out: number
        Standard deviation.

    Examples
    --------
    > var y = {{alias}}( 4.0, 2.0, 1.0 )
    ~1.041
    > var y = {{alias}}( 4.0, 2.0, -3.0 )
    ~1.041
    > y = {{alias}}( 0.5, 2.0, 1.0 )
    Infinity
    > y = {{alias}}( NaN, 1.0, 0.0 )
    NaN
    > y = {{alias}}( 1.0, NaN, 0.0 )
    NaN
    > y = {{alias}}( 1.0, 1.0, NaN )
    NaN
