bool	vtkMathUtilities::FuzzyCompare (A a, A b, A epsilon=std::numeric_limits< A >::epsilon())
	Perform a fuzzy compare of floats/doubles, specify the allowed tolerance.
template<class A >
A	vtkMathUtilities::SafeDivision (A a, A b)
	Performs safe division that catches overflow and underflow.
template<class A >
