{{alias}}( x, α, s, m )
    Evaluates the cumulative distribution function (CDF) for a Fréchet
    distribution with shape parameter `α`, scale parameter `s`, and location
    `m`.

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

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

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

    α: number
        Shape parameter.

    s: number
        Scale parameter.

    m: number
        Location parameter.

    Returns
    -------
    out: number
        Evaluated CDF.

    Examples
    --------
    > var y = {{alias}}( 10.0, 2.0, 3.0, 0.0 )
    ~0.914
    > y = {{alias}}( -1.0, 2.0, 3.0, -3.0 )
    ~0.105
    > y = {{alias}}( 2.5, 2.0, 1.0, 2.0 )
    ~0.018
    > y = {{alias}}( NaN, 1.0, 1.0, 0.0 )
    NaN
    > y = {{alias}}( 0.0, NaN, 1.0, 0.0 )
    NaN
    > y = {{alias}}( 0.0, 1.0, NaN, 0.0 )
    NaN
    > y = {{alias}}( 0.0, 1.0, 1.0, NaN )
    NaN
    > y = {{alias}}( 0.0, -1.0, 1.0, 0.0 )
    NaN
    > y = {{alias}}( 0.0, 1.0, -1.0, 0.0 )
    NaN


{{alias}}.factory( α, s, m )
    Returns a function for evaluating the cumulative distribution function (CDF)
    of a Fréchet distribution with shape parameter `α`, scale parameter `s`, and
    location `m`.

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

    s: number
        Scale parameter.

    m: number
        Location parameter.

    Returns
    -------
    cdf: Function
        Cumulative distribution function (CDF).

    Examples
    --------
    > var myCDF = {{alias}}.factory( 3.0, 3.0, 5.0 );
    > var y = myCDF( 10.0 )
    ~0.806
    > y = myCDF( 7.0 )
