Classes
class	ROOT::Math::KahanSum< T, N >
	The Kahan summation is a compensated summation algorithm, which significantly reduces numerical errors when adding a sequence of finite-precision floating point numbers. More...
class	ROOT::Math::Util::TimingScope

Namespaces
namespace	ROOT
	tbb::task_arena is an alias of tbb::interface7::task_arena, which doesn't allow to forward declare tbb::task_arena without forward declaring tbb::interface7
namespace	ROOT::Math
namespace	ROOT::Math::Util
	namespace defining Utility functions needed by mathcore

Macros
#define	MATH_UNUSED(var)   (void)var

Functions
template<class T >
T	ROOT::Math::Util::EvalLog (T x)
	safe evaluation of log(x) with a protections against negative or zero argument to the log smooth linear extrapolation below function values smaller than epsilon (better than a simple cut-off)
template<typename T , unsigned int N, typename U , unsigned int M>
KahanSum< T, N >	ROOT::Math::operator+ (const KahanSum< T, N > &left, const KahanSum< U, M > &right)
	Add two non-vectorized KahanSums.
template<typename T , unsigned int N, typename U , unsigned int M>
KahanSum< T, N >	ROOT::Math::operator- (const KahanSum< T, N > &left, const KahanSum< U, M > &right)
	Subtract two non-vectorized KahanSums.
template<class T >
std::string	ROOT::Math::Util::ToString (const T &val)
	Utility function for conversion to strings.
