Functions
template<class A >
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 >
bool	vtkMathUtilities::NearlyEqual (A a, A b, A tol=std::numeric_limits< A >::epsilon())
	A slightly different fuzzy comparator that checks if two values are "nearly" equal based on Knuth, "The Art of Computer Programming (vol II)".
template<class A >
void	vtkMathUtilities::UpdateRangeImpl (A &min0, A &max0, const A &value)
	Update an existing min - max range with a new prospective value.
