Detailed Description

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

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

Note

This specialisation is enabled if To is an integral type, piranha::mp_integer or piranha::mp_rational, and From is piranha::real.

Member Function Documentation

operator()() [1/2]

template<typename To , typename From >

template<typename T = To, integral_enabler< T > = 0>

T piranha::safe_cast_impl< To, From, sc_real_enabler< To, From > >::operator() ( const real &  r ) const

inline

Call operator, real to integral overload.

Note

This operator is enabled if To is an integral type or an instance of piranha::mp_integer.

The conversion will succeed if r is a finite integral value representable by the target type.

Parameters

r	conversion argument.

Returns

r converted to To.

Exceptions

piranha::safe_cast_failure	if the conversion fails.
unspecified	any exception thrown by boost::lexical_cast().

Definition at line 2293 of file real.hpp.

operator()() [2/2]

template<typename To , typename From >

template<typename T = To, rational_enabler< T > = 0>

T piranha::safe_cast_impl< To, From, sc_real_enabler< To, From > >::operator() ( const real &  r ) const

inline

Call operator, real to rational overload.

Note

This operator is enabled if To is an instance of piranha::mp_rational.

Parameters

r	conversion argument.

Returns

r converted to piranha::mp_rational.

Exceptions

piranha::safe_cast_failure	if the conversion fails.
unspecified	any exception thrown by boost::lexical_cast().
