binomial_coef()

template<typename T1 , typename T2 >

constexpr common_t< T1, T2 > binomial_coef ( const T1  n, const T2  k  )

constexprnoexcept

Compile-time binomial coefficient.

Parameters

n	integral-valued input.
k	integral-valued input.

Returns

computes the Binomial coefficient

\[ \binom{n}{k} = \frac{n!}{k!(n-k)!} \]

also known as 'n choose k '.
