quantile
Returns the quantile (inverse CDF) for the given probability p as a Double.
Delegates to quantileInt and converts the result to Double. This override satisfies the Distribution interface contract. Prefer quantileInt when an integer result is needed.
Return
the smallest value at which cdf(x) >= p, as a Double.
Parameters
p
the cumulative probability, must be in [0, 1].
Throws
if p is not in [0, 1].
