binomial(n::Integer, k::Integer)

The _binomial coefficient_ ``\binom{n}{k}``, being the coefficient of the ``k``th term in
The _binomial coefficient_ ``\\binom{n}{k}``, being the coefficient of the ``k``th term in
the polynomial expansion of ``(1+x)^n``.

If ``n`` is non-negative, then it is the number of ways to choose `k` out of `n` items:
```math
\binom{n}{k} = \frac{n!}{k! (n-k)!}
\\binom{n}{k} = \\frac{n!}{k! (n-k)!}
```
where ``n!`` is the [`factorial`](@ref) function.

If ``n`` is negative, then it is defined in terms of the identity
```math
\binom{n}{k} = (-1)^k \binom{k-n-1}{k}
\\binom{n}{k} = (-1)^k \\binom{k-n-1}{k}
```
