Returns the cumulative distribution function, its inverse, or one of its parameters,
of the binomial distribution. The kind of the return value and parameters
(par1
, par2
, and par3
)
are determined by which

The following table lists the return value and parameters by which
.
CDF, x, n, and p denotes cumulative distribution function, the number of successes,
the number of trials, and the success rate for each trial, respectively.
