Classes
class	ROOT::Math::KahanSum< T >
	The Kahan compensate summation algorithm significantly reduces the numerical error in the total obtained by adding a sequence of finite precision floating point numbers. This is done by keeping a separate running compensation (a variable to accumulate small errors). . More...

Functions

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) More...
