Feature< Feature_type, typename std::enable_if< std::is_floating_point< Feature_type >::value, void >::type > Class Template Reference

Detailed Description

template<typename Feature_type>
class HepMC3::Feature< Feature_type, typename std::enable_if< std::is_floating_point< Feature_type >::value, void >::type >

specialisation of Feature for floating point type

Test of equality of floating point types is not safe. Here we provide a "reasonable" definition of equality based on the floating point precision.
