{{alias}}( N, K, n )
    Returns the standard deviation of a hypergeometric distribution.

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

    If provided a population size `N`, subpopulation size `K` or draws `n` which
    is not a nonnegative integer, the function returns `NaN`.

    If the number of draws `n` or the subpopulation size `K` exceed population
    size `N`, the function returns `NaN`.

    Parameters
    ----------
    N: integer
        Population size.

    K: integer
        Subpopulation size.

    n: integer
        Number of draws.

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

    Examples
    --------
    > var v = {{alias}}( 16, 11, 4 )
    ~0.829
    > v = {{alias}}( 2, 1, 1 )
    0.5

    > v = {{alias}}( 10, 5, 12 )
    NaN
    > v = {{alias}}( 10.3, 10, 4 )
