#define itkTemplateFloatingToIntegerMacro (   name)
template< typename TReturn, typename TInput > \
inline TReturn name(TInput x) \
{ \
if ( sizeof( TReturn ) <= 4 ) \

return static_cast< TReturn >( Detail::name##_32(x) ); \

} \

} \

A useful macro to generate a template floating point to integer conversion templated on the return type and using either the 32 bit, the 64 bit or the vanilla version
