Numerical Evaluation & Precision
In two decades of intense algorithmic development, Mathematica has established a new level of numerical computation. Particularly notable are its many original highly efficient algorithms, its methodology for automatic algorithm selection, and its systemwide support for automatic error tracking and arbitrary-precision arithmetic.
