Detailed Description

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

Specialisation of piranha::safe_cast() for C++ floating-point to C++ integral conversions.

Note

This specialisation is enabled if From is a C++ floating-point type and To is a C++ integral type.

Member Function Documentation

operator()()

template<typename To , typename From >

To piranha::safe_cast_impl< To, From, sc_float_to_int_enabler< To, From > >::operator() ( const From &  f ) const

inline

Call operator.

The call operator will first check that f is a finite integral value, and it will then invoke boost::numeric_cast() to perform the conversion.

Parameters

f	conversion argument.

Returns

f safely converted to To.

Exceptions

piranha::safe_cast_failure

if: f is not finite or it has a nonzero fractional part, boost::numeric_cast() raises an error.
