{{alias}}( x, p )
    Evaluates the cumulative distribution function (CDF) for a geometric
    distribution with success probability `p` at a value `x`.

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

    If `p < 0` or `p > 1`, the function returns `NaN`.

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

    p: number
        Success probability.

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

    Examples
    --------
    > var y = {{alias}}( 2.0, 0.5 )
    0.875
    > y = {{alias}}( 2.0, 0.1 )
    ~0.271
    > y = {{alias}}( -1.0, 4.0 )
    0.0
    > y = {{alias}}( NaN, 0.5 )
    NaN
    > y = {{alias}}( 0.0, NaN )
    NaN
    // Invalid probability
    > y = {{alias}}( 2.0, 1.4 )
    NaN


{{alias}}.factory( p )
    Returns a function for evaluating the cumulative distribution function (CDF)
    of a geometric distribution with success probability `p`.

    Parameters
    ----------
    p: number
        Success probability.

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

    Examples
    --------
    > var mycdf = {{alias}}.factory( 0.5 );
    > var y = mycdf( 3.0 )
    0.9375
    > y = mycdf( 1.0 )
    0.75
