Detailed Description

template<typename T, typename = void>
struct piranha::math::invert_impl< T, typename >

Default functor for the implementation of piranha::math::invert().

This functor should be specialised via the std::enable_if mechanism. The call operator will call piranha::math::pow() with an exponent of -1, and it is enabled only if integral exponentiation is supported by the argument type.
