| 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 NB: this uses an absolute tolerance.

| template<class A > |
| A | vtkMathUtilities::SafeDivision (A a, A b) |
| | Performs safe division that catches overflow and underflow.

| 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)" NB: this uses a relative tolerance.
