Detailed Description

template<typename To, typename From>
struct piranha::safe_cast_impl< To, From, sc_rat_enabler< To, From > >

Specialisation of piranha::safe_cast() for conversions involving piranha::mp_rational.

Note

This specialisation is enabled in the following cases:

• To is a rational type and From is either an arithmetic type or piranha::mp_integer,
• To is an integral type or piranha::mp_integer, and From is piranha::mp_rational.
