Specialisation of the implementation of piranha::math::pow() for piranha::mp_rational.
This specialisation is activated when one of the arguments is piranha::mp_rational and the other is either piranha::mp_rational or an interoperable type for piranha::mp_rational.
The implementation follows these rules:
- if the base is rational and the exponent an integral type or piranha::mp_integer, then piranha::mp_rational::pow() is used;
- if the non-rational argument is a floating-point type, then the rational argument is converted to that floating-point type and piranha::math::pow() is used;
- if both arguments are rational the result will be rational and the success of the operation depends on the values of the operands;
- if the base is an integral type or piranha::mp_integer and the exponent a rational, the result is computed via the integral–integer specialisation of piranha::math::pow() and the the success of the operation depends on the values of the operands.
