Functions
template<class T >
bool	jau::in_range (const T &a, const T &b, const T &delta)
	Returns true, if both integer point values differ less than the given delta. More...
template<class T >
std::enable_if<!std::numeric_limits< T >::is_integer, T >::type	jau::machineEpsilon ()
	Calculates the smallest floating point value approximation the given type T can represent, the machine epsilon of T. More...
template<class T >
std::enable_if<!std::numeric_limits< T >::is_integer, bool >::type	jau::machine_equal (const T &a, const T &b, int ulp=1, const T &epsilon=std::numeric_limits< T >::epsilon())
	Returns true, if both floating point values are equal in the sense that their potential difference is less or equal epsilon * ulp. More...
template<class T >
std::enable_if<!std::numeric_limits< T >::is_integer, bool >::type	jau::almost_equal (const T &a, const T &b, int ulp=1, const T &epsilon=std::numeric_limits< T >::epsilon())
	Returns true, if both floating point values are equal in the sense that their potential difference is less or equal epsilon * |a+b| * ulp, where |a+b| scales epsilon to the magnitude of used values. More...
