Detailed Description

template<typename T, typename U>
struct piranha::math::binomial_impl< T, U, integer_binomial_enabler< T, U > >

Specialisation of the implementation of piranha::math::binomial() for piranha::mp_integer.

This specialisation is activated when:

• one of the arguments is a piranha::mp_integer and the other is either a piranha::mp_integer with the same static size or an interoperable type for piranha::mp_integer,
• both arguments are integral types.

The implementation follows these rules:

• if the arguments are both piranha::mp_integer with the same static size, or a piranha::mp_integer and an integral type, then piranha::mp_integer::binomial() is used to compute the result (after any necessary conversion),
• if both arguments are integral types, piranha::mp_integer::binomial() is used after the conversion of the top argument to piranha::integer,
• otherwise, the piranha::mp_integer argument is converted to the floating-point type and piranha::math::binomial() is used to compute the result.
