Detailed Description

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

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

Note

This specialisation is enabled in the following cases:

• To is an instance of piranha::mp_integer and From is a C++ floating-point type from which piranha::mp_integer can be constructed,
• To is an instance of piranha::mp_integer and From is a C++ integral type from which piranha::mp_integer can be constructed,
• From is an instance of piranha::mp_integer and To is a C++ integral type constructible from piranha::mp_integer.

Member Function Documentation

operator()()

template<typename To , typename From >

To piranha::safe_cast_impl< To, From, mp_integer_safe_cast_enabler< To, From > >::operator() ( const From &  x ) const

inline

Call operator.

Parameters

x	input value to be converted.

Returns

x converted to To.

Exceptions

piranha::safe_cast_failure	if: the input float is not finite or if it has a nonzero fractional part, the target integral type To cannot represent the value of the input piranha::mp_integer.
unspecified	any exception thrown by the constructor of piranha::mp_integer from a floating-point.
