However, *do not panic*, both definition and usage are not really very different.

(If you find slightly different values, the Boost C++ version, using double or better,
is very likely to be the more accurate.
Of course, accuracy is not usually a concern for most applications of this function).

The equivalent using this Boost C++ library is:

using namespace boost::math; // Using declaration avoids very long names.

binomial my_dist(4, 0.5); // c.f. NAG n = 4, p = 0.5

`cdf(dist, k)` is equivalent to NAG library `plek`, lower tail probability of <= k

`cdf(complement(dist, k))` is equivalent to NAG library `pgtk`, upper tail probability of > k

`pdf(dist, k)` is equivalent to NAG library `peqk`, point probability of == k
